The Short Answer
Managed hosting with CPU of its own is much faster under load than shared hosting. Managed WordPress by itself is not. I put the same WordPress test site on 13 plans, eight shared and five sold as managed, and measured each the same way. For a single visitor, the good shared plans were close to the managed ones: ChemiCloud's shared Starter answered in 84ms from New York, US. With 100 visitors at once the gap opened: ScalaHosting's managed VPS held 58ms, Cloudways 74ms and Kinsta 92ms, while the shared plans ran from 240ms to 1400ms.
Two managed WordPress plans sat among the shared ones: WP Engine Startup at 487ms and Namecheap EasyWP Starter at 1300ms. What you pay for is capacity, not the word "managed".

See ScalaHostingHow We Tested
- One plan per host, one test site. The same WordPress site on each plan, with the host's own caching left as it ships.
- Response time (TTFB) from 10 locations, measured at the origin server with no CDN in front, so the figure is the server's own.
- Load: a ramp from 0 to 250 clients at once. We report the response at the 100-user step and the share of requests that failed over the whole ramp. SiteGround's test ramped to 100 clients.
- Uptime checked every minute for 54 days.
Eight plans are shared hosting: ChemiCloud, Hostinger, SiteGround, DreamHost, InMotion, Hosting.com, Bluehost and HostGator. Five are sold as managed: ScalaHosting's managed VPS, a Cloudways server, and the managed WordPress plans from Kinsta, WP Engine and Namecheap EasyWP. Prices come from each host's own pricing page and are re-read from our price records every time this page is built. Full method: How We Test. The same figures, with scores, are in our WordPress hosting guide.
What Is Shared Hosting?
Shared hosting puts many accounts on one server. They share its CPUs, memory, disks and network, and the host keeps the peace with per-account limits. It is the apartment building of hosting: cheap because the costs are split, but the walls are thin.
"Unlimited" on a shared plan usually refers to bandwidth or storage. The limits that decide speed are elsewhere, and a good host publishes them:
- CPU: how much processor time your account may use, often as a number of cores.
- Memory: the RAM your account's processes may use together.
- Processes: how many PHP workers or entry processes may run at once.
- Files: an inode limit on the number of files, which catches large backups and caches.
Hostinger is one of the few hosts that publishes every limit. The Premium plan we tested gets one CPU core, 2GB of memory and 40 PHP workers. ChemiCloud's WordPress Starter lists one core and 2GB as well.
Shared hosting is built for sites that are quiet most of the time: blogs, brochure sites, portfolios, staging copies. For those, a good shared plan is fast and the price is hard to beat.
What Is Managed WordPress Hosting?
"Managed" means the host looks after the server and, to a degree, WordPress for you. It is sold in two quite different forms:
- Managed WordPress platforms, such as Kinsta, WP Engine and EasyWP: you get a dashboard for your WordPress sites and never see the server. How much CPU sits behind your plan is rarely published.
- Managed servers, such as ScalaHosting's managed VPS and Cloudways: you get a server of your own, with a set number of CPUs and memory, and the host runs it for you.
What the host manages varies, but it usually covers the operating system and its security patches, the web server and PHP versions, SSL certificates, a firewall, and automatic backups. Many add WordPress tools on top: one-click staging, update management and malware scanning. Check which of these your plan includes; some are add-ons.
The software stack is similar on both sides: a web server (Apache, NGINX or LiteSpeed), PHP, a database, and page and object caches. What differs is how much of the machine is yours when many requests arrive at once, and that is what the load test below measures.
TTFB: One Visitor at a Time
Time to first byte (TTFB) is how long the server takes to start answering. Every other step of a page load waits on it. We measured it from 10 locations with no CDN in front, so the figure is the server's own.
| Host and plan | Type | TTFB, nearest location | Average of 10 locations |
|---|---|---|---|
| ScalaHosting Entry Cloud (managed VPS) | Managed VPS | 38ms New York, US | 84ms |
| Cloudways Vultr High Frequency 4GB | Managed cloud server | 48ms New York, US | 106ms |
| Kinsta Single 20GB | Managed WordPress | 64ms New York, US | 143ms |
| WP Engine Startup | Managed WordPress | 242ms New York, US | 540ms |
| Namecheap EasyWP Starter | Managed WordPress | 344ms New York, US | 769ms |
| ChemiCloud Starter (shared) | Shared | 84ms New York, US | 187ms |
| Hostinger Premium (shared) | Shared | 109ms Frankfurt, DE | 252ms |
| SiteGround StartUp (shared) | Shared | 123ms Frankfurt, DE | 285ms |
| Hosting.com Turbo Boost (shared) | Shared | 152ms New York, US | 339ms |
| InMotion Launch (shared) | Shared | 210ms New York, US | 469ms |
| DreamHost Shared Starter | Shared | 230ms New York, US | 513ms |
| Bluehost Basic, now sold as Starter | Shared | 287ms New York, US | 641ms |
| HostGator Hatchling | Shared | 332ms New York, US | 742ms |
Lower is better. The nearest location is the test location closest to where the host put our site.
For one visitor, the type of hosting mattered less than the host. ChemiCloud's shared plan (84ms) and Hostinger's (109ms from Frankfurt, DE) beat WP Engine's managed Startup (242ms). The fastest three were all managed plans with dedicated resources, but a good shared plan on a current CPU gave a single visitor a fast answer too.
Google suggests a TTFB of 800ms or less as a rough guide for good page experience. Every plan here met that for its nearest location; the slowest ones did not from the far side of the world, which is where a CDN helps.
Load Test: 100 Visitors at Once
This is where shared and managed hosting really part. We ramped each plan from 0 to 250 clients requesting pages at the same time, and recorded the response at the 100-user step and every failed request over the ramp.
| Host and plan | Type | One visitor, nearest location | 100 concurrent users | Failed requests, full ramp |
|---|---|---|---|---|
| ScalaHosting Entry Cloud (managed VPS) | Managed VPS | 38ms | 58ms | 0% |
| Cloudways Vultr High Frequency 4GB | Managed cloud server | 48ms | 74ms | 0% |
| Kinsta Single 20GB | Managed WordPress | 64ms | 92ms | 0% |
| ChemiCloud Starter (shared) | Shared | 84ms | 240ms | 0% |
| WP Engine Startup | Managed WordPress | 242ms | 487ms | 0% |
| Hostinger Premium (shared) | Shared | 109ms | 520ms | 0.8% |
| Hosting.com Turbo Boost (shared) | Shared | 152ms | 534ms | 0.3% |
| DreamHost Shared Starter | Shared | 230ms | 620ms | 0.5% |
| InMotion Launch (shared) | Shared | 210ms | 660ms | 0.38% |
| SiteGround StartUp (shared) | Shared | 123ms | 900ms | 5% |
| HostGator Hatchling | Shared | 332ms | 980ms | 35.78% |
| Namecheap EasyWP Starter | Managed WordPress | 344ms | 1300ms | 2.56% |
| Bluehost Basic, now sold as Starter | Shared | 287ms | 1400ms | 42.84% |
Lower is better. A load-test client asks for pages continuously, so 100 clients are far busier than 100 people reading. SiteGround's test ramped to 100 clients instead of 250, so its run completed fewer requests than the others, 3,300 against 8,250.
Three managed plans stayed under 100ms with 100 users and failed nothing. The best shared plan, ChemiCloud, slowed to 240ms but also failed nothing. Further down, Bluehost and HostGator failed 42.84% and 35.78% of all requests as the ramp climbed, which is what visitors see as error pages.
WP Engine Startup (487ms) and EasyWP Starter (1300ms, 2.56% failed) are the reason this page does not say "managed is faster". Both are sold as managed WordPress, and both behaved like shared plans under load.
PHP Workers and CPU Cores
A cached page is a file the server hands back. An uncached one, a cart, a checkout, a search, a logged-in page or anything in wp-admin, has to be built by PHP, and that takes a PHP worker and CPU time. A worker builds one page at a time; when every worker is busy, the next request waits, and a long wait ends in a 503 or 504 error.
You will often read that shared hosting gives you only two to four workers. Hostinger shows why that rule of thumb misleads: its Premium plan lists 40 workers on one CPU core. A worker needs a core to run on, so under load forty workers take turns on one core. That is what our test measured: 109ms for one visitor, 520ms with 100. The limit that bites on shared hosting is the CPU, not the worker count.
| Plan we tested | Type | CPU | Memory | PHP workers |
|---|---|---|---|---|
| ScalaHosting Entry Cloud | Managed VPS | 2 dedicated CPUs | 2GB | not published |
| Cloudways Vultr HF 4GB | Managed cloud server | 2 vCPU, your own server | 4GB | Your server's, not shared |
| Kinsta Single 20GB | Managed WordPress | not published | not published | Extra threads sold as an add-on |
| ChemiCloud WordPress Starter | Shared | 1 core | 2GB | not published |
| Hostinger Premium | Shared | 1 core | 2GB | 40 |
From each host's own plan page. Most hosts publish none of these numbers, and that is worth knowing in itself; the load test is how we see what a plan really gets.
On managed WordPress platforms, PHP capacity is metered instead. Kinsta sells extra PHP threads and memory as a monthly add-on, and describes the signs of running out as requests queuing or timing out. If your store is growing, price that in.
CPU, Memory and "Unlimited"
PHP runs mostly on one CPU core per request, so the speed of each core decides how long an uncached page takes to build, and the number of cores decides how many can be built at once. We identified the server CPU under each plan and looked up its PassMark rank. ScalaHosting's AMD EPYC 9474F ranks #42 and ChemiCloud's AMD EPYC 9354 #110; at the other end, Bluehost's Intel Xeon E5-2680 v3 ranks #1,343.
A fast CPU explains why a shared plan like ChemiCloud's can answer one visitor quickly. It does not change how many cores your account may use at once, which is why the same plan slowed under load while the managed VPS on two dedicated CPUs did not.
Memory works the same way. The PHP memory limit is the most one request may use; the plan's RAM is what all your requests, the database and any object cache share. Hostinger Premium allows a single PHP request 1,536MB, but the whole plan has 2GB, so running out of the shared pool is what stops you, not the per-request limit. On a managed server the memory is yours, so a busy neighbour cannot take it.
Uptime Over 54 Days
We checked every plan once a minute for 54 days. All of them stayed up more than 99.8% of the time; the differences are measured in minutes.
| Host and plan | Type | Uptime | Downtime | Incidents |
|---|---|---|---|---|
| ScalaHosting Entry Cloud (managed VPS) | Managed VPS | 99.99% | 8 min | 2 |
| Cloudways Vultr High Frequency 4GB | Managed cloud server | 99.99% | 8 min | 2 |
| Kinsta Single 20GB | Managed WordPress | 99.99% | 8 min | 2 |
| WP Engine Startup | Managed WordPress | 99.97% | 23 min | 3 |
| ChemiCloud Starter (shared) | Shared | 99.97% | 23 min | 3 |
| SiteGround StartUp (shared) | Shared | 99.97% | 23 min | 3 |
| Hostinger Premium (shared) | Shared | 99.95% | 39 min | 3 |
| DreamHost Shared Starter | Shared | 99.94% | 47 min | 3 |
| InMotion Launch (shared) | Shared | 99.931% | 54 min | 3 |
| Hosting.com Turbo Boost (shared) | Shared | 99.931% | 54 min | 3 |
| Namecheap EasyWP Starter | Managed WordPress | 99.92% | 62 min | 3 |
| Bluehost Basic, now sold as Starter | Shared | 99.9% | 78 min | 3 |
| HostGator Hatchling | Shared | 99.87% | 101 min | 4 |
Over the same 54-day window for every plan, with a check every minute.
The managed plans with dedicated resources had the least downtime, 8 minutes each, and the shared plans ranged from 23 to 101 minutes. Put a price on it: a site that earns $10,000 a month earns about $0.23 a minute, so the 93-minute gap between ScalaHosting and HostGator was worth about $21.53 over the whole window. Downtime at this level is cheap. Slow pages and failed requests during a busy hour, as in the load test, cost far more.
WooCommerce and Other Dynamic Sites
A store is the hardest job for a host. Product pages can be cached, but the cart, checkout and account pages cannot: each one runs PHP, reads and writes the database, and waits on a worker and a CPU core. The same is true of membership sites, courses, forums and anything with many people logged in.
That makes the load test the part of our benchmark that matters most for a store. With 100 clients at once, the managed plans with dedicated CPU answered in 58ms to 92ms and failed nothing; the shared plans took 240ms to 1400ms, and two of them failed more than a third of requests as the ramp kept climbing. A failed request during checkout is a lost order.
We also ran a separate store test, with real carts and checkouts, on the plans in our WooCommerce hosting guide. Our rule of thumb: a small store with occasional orders can start on a good shared plan such as ChemiCloud; once shoppers regularly arrive together, move to a plan with CPU of its own.
Security
Shared hosting's security weakness is the shared part. Accounts on one server are isolated from each other, but they share an IP address, and a neighbour who sends spam or gets hacked can get that address blocklisted. A flood of traffic aimed at one site can slow every site on the server.
On a managed plan your site is either on its own server or in its own container, and the host runs the security layer for you: a firewall, malware scanning, and usually cleanup if something gets in.
On shared hosting, scanning and cleanup are often sold separately. Bluehost's SiteLock Essentials renews at $95.88 a year, GoDaddy's Website Security starts at $6.99 a month, and even Cloudways charges from $4.00 per app a month for its malware protection. Our hidden hosting fees guide lists the free alternatives.
Control Panels
Most shared hosting runs cPanel, and most managed WordPress runs the host's own dashboard.
- cPanel is the standard: files, email, databases, domains and an app installer for WordPress. It works the same at every host that sells it, which makes moving easy. Its licence is priced per server, and the host passes that cost on.
- SPanel is ScalaHosting's own panel and covers what most people use cPanel for: files, email, databases, DNS, SSL and WordPress installs. It is included with the plan, but only runs at ScalaHosting.
- Managed WordPress dashboards, such as MyKinsta or the Cloudways platform, are built around your WordPress sites: staging, backups, caching and PHP settings in a few clicks. Email and DNS are often outside them.
If you only run WordPress, a WordPress dashboard is usually easier than cPanel. If you also need email and other apps on the same account, cPanel or SPanel keeps everything in one place.
What It Costs Over Three Years
The advertised price is the first term. Shared hosting has the biggest jump at renewal; most managed plans charge the same, or close to it, every year.
| Host and plan | Type | First term | Renewal | Term | First three years |
|---|---|---|---|---|---|
| ChemiCloud Starter | Shared | $2.95/mo | $11.95/mo | 36 months | $106.20 |
| Hostinger Premium | Shared | $2.99/mo | $10.99/mo | 36 months | $107.64 |
| SiteGround StartUp | Shared | $3.99/mo | $17.99/mo | 12 months | $479.64 |
| Bluehost Starter | Shared | $3.99/mo | $9.99/mo | 36 months | $143.64 |
| ScalaHosting Entry Cloud | Managed VPS | $24.95/mo | $39.95/mo | 36 months | $898.20 |
| Cloudways Vultr HF 1GB | Managed cloud server | $16.00/mo | $16.00/mo | month-to-month | $576.00 |
| Kinsta Single 20GB | Managed WordPress | $29.17/mo | $29.17/mo | 12 months | $1,050.12 |
| WP Engine Startup | Managed WordPress | $25.00/mo | $25.00/mo | 12 months | $900.00 |
Each plan on the term that costs least over three years; "first three years" is the first term at the intro price and the rest at renewal. SiteGround is sold here on 12 months only. Cloudways is shown on its entry Vultr High Frequency server; we tested the 4GB size.
The renewal step on the shared plans is steep: Hostinger Premium goes from $2.99/mo to $10.99/mo after its 36-month term, SiteGround StartUp from $3.99/mo to $17.99/mo after 12 months. Long terms keep the shared plans cheap for three years, which is why the table uses them. Kinsta and WP Engine renew at the price you started on. Over three years the gap between a good shared plan and a managed one is still several hundred dollars, so buy the managed plan for what it does under load, not because the shared renewal looks bad.
Add the extras before you compare: a mailbox service if your plan has no email (Cloudways sells Rackspace mail at $1.50 per mailbox a month), paid backups or security on the shared side, and visit or bandwidth overage on metered managed plans.
When to Move Up
Monthly visits are a poor guide, because what strains a plan is how many requests arrive together and how many skip the cache. An example with round numbers: 30,000 visits a month is about 1,000 a day. If a tenth of them come in the busiest hour and each stays three minutes, about five people are on the site at once. A cached blog of that size is fine on a good shared plan. A store of that size, with five people in their carts, is a different load.
Signs you have outgrown shared hosting:
- Pages slow down, or show 503 and 508 errors, when a newsletter or a sale goes out
- Your control panel's resource page shows the CPU or process limit being hit
- wp-admin, carts and checkout feel slow even when the front page is quick
- The site earns money, and a slow hour costs more than the price difference
When you move, move to CPU of your own. On our benchmark that was ScalaHosting's Entry Cloud (58ms with 100 users), a Cloudways server (74ms) or Kinsta (92ms). A managed WordPress plan that does not say what it gives you may not be an upgrade at all.
Moving From Shared to Managed
Moving a WordPress site is routine, and many hosts do it for you: Hostinger lists free automatic website migration, and Bluehost offers a free migration tool on every plan. The steps are the same either way.
- A day before: lower the DNS TTL on your domain to a few minutes, so the switch spreads quickly.
- Copy: files and database to the new server, with the same PHP version or a newer one your plugins support.
- Test: on the host's temporary address or through your hosts file. Check forms, logins, the cart and checkout, and run a speed test.
- Switch: point the domain at the new server. For a store, pause orders for the final sync so none land on the old server.
- Keep the old plan for a few days as a fallback, then cancel it before it renews.
Most problems after a move come from a PHP version change, a hard-coded path, or a caching plugin set up for the old host. Clear the caches and check the error log first.

Best Managed Plans We Tested
1. ScalaHosting Entry Cloud (managed VPS)
The fastest plan on our benchmark with 100 users: 58ms, no failed requests, and 38ms for one visitor from New York, US. Two dedicated CPUs on an AMD EPYC 9474F, the fastest server CPU we found under any host (PassMark #42). SPanel and email are included. $14.95/mo on 12 months or $24.95/mo on 36, renewing at $39.95/mo.
See ScalaHosting ScalaHosting review
2. Cloudways
A managed cloud server you choose yourself, billed by the month. On the Vultr High Frequency 4GB server we tested: 48ms from New York, US, 74ms with 100 users, no failed requests. Good for developers and for several sites on one server. There is no email or cPanel; mail is an add-on. The entry Vultr High Frequency server is $16.00/mo; current codes are on our Cloudways promo code page.
See Cloudways Cloudways review
3. Kinsta Single 20GB
A polished managed WordPress platform on Google Cloud: 64ms from New York, US, 92ms with 100 users, no failed requests, on an AMD EPYC 7502. The plan is one WordPress site with a traffic allowance, and more PHP capacity is a paid add-on. $29.17/mo billed yearly or $35.00/mo month to month, the same at renewal.
Also tested: WP Engine Startup (487ms with 100 users, $25.00/mo billed yearly) and Namecheap EasyWP Starter (1300ms, $3.24/mo). Both are managed WordPress, and both were slower under load than ChemiCloud's shared plan.
What This Comparison Does Not Cover
- Support. We measured servers, not how quickly each host answers a ticket.
- Checkout timings on every plan. Our store test covers the plans in the WooCommerce hosting guide; here the load test stands in for it.
- Bigger plans. We tested each host's entry or featured plan. Larger shared and managed plans have more resources and can behave differently.
FAQ: Shared vs Managed WordPress Hosting
Is managed WordPress hosting worth the extra cost?
For a busy or revenue-earning site, the right managed plan is. On our benchmark the three best managed plans answered in 58ms to 92ms with 100 concurrent users, while the best shared plan took 240ms and the slowest 1400ms. For a small blog that serves cached pages, a good shared plan such as ChemiCloud Starter ($2.95/mo on 36 months) is enough, and the extra money buys little you would notice.
Is every managed WordPress plan faster than shared hosting?
No. The label describes the service, not the server. WP Engine Startup answered in 487ms with 100 concurrent users and Namecheap EasyWP Starter in 1300ms, slower than ChemiCloud's shared Starter at 240ms. What separated the fast plans was CPU capacity of their own: ScalaHosting's Entry Cloud has two dedicated CPUs and the Cloudways server we tested has two vCPUs to itself.
Can I host WooCommerce on shared hosting?
A small store, yes, on a good shared plan. Carts, checkout and account pages cannot be served from the page cache, so every shopper uses PHP and CPU time. On our load test the shared plans ranged from 240ms to 1400ms with 100 concurrent users, and two of them failed more than a third of requests as the load kept rising. Once shoppers regularly arrive together, move to a plan with dedicated CPU. Our WooCommerce hosting guide has the store test.
How many visitors can shared hosting handle?
Monthly visits are the wrong measure; what matters is how many requests arrive at the same moment and how many of them skip the cache. A site with 30,000 visits a month often has only a handful of people on it at once, and a cached blog of that size runs fine on a good shared plan. The trouble starts with bursts: a newsletter, a sale or a post that takes off. Our test pushed 100 clients at once, and that is where the shared plans slowed to 240ms and beyond.
What are PHP workers and why do they matter?
A PHP worker builds one uncached page at a time. When every worker is busy, the next request waits, and a long wait ends in a 503 or 504 error. The count alone can mislead: Hostinger Premium lists 40 PHP workers, but they share one CPU core, so under load they wait for the CPU. That is why it answered in 109ms for one visitor and 520ms with 100. CPU cores decide how many pages can really be built at once.
Will managed hosting improve my SEO?
It can help page speed, which is part of how Google judges page experience, but it is not a ranking switch. A faster server shortens the time to first byte, which every other load step waits on. Our fastest plans answered in under 64ms from the nearest test location; the slowest shared plans took over 287ms. Good content and caching still matter more than the plan type.
Can I move from shared to managed hosting easily?
Yes. For a WordPress site it is a copy of the files and the database, a test on a temporary address, and a DNS change. Many hosts include a migration: Hostinger lists free automatic website migration and Bluehost a free migration tool, for example. Lower your DNS TTL a day before, keep the old plan for a few days after the switch, and check forms and checkout on the new server before you move DNS.
Does managed WordPress include email?
It depends on the host. SPanel on ScalaHosting includes email. Cloudways sells Rackspace email as an add-on at $1.50 per mailbox a month. Many managed WordPress platforms leave email out, so price a mailbox service in before you compare.
Why is my shared hosting slow at busy times?
On shared hosting your plan's CPU and memory limits apply to everything your site does, and the server itself is shared with other accounts. When your own traffic rises, requests queue for your plan's CPU; when neighbours are busy, the whole server can be slower. Our load test shows the first effect clearly: the shared plans answered one visitor in 84ms to 332ms, and 100 at once in 240ms to 1400ms.
What I Would Choose
For a new blog, a brochure site or anything that caches well, I would start on ChemiCloud's shared Starter at $2.95/mo on 36 months. It was the best shared plan we tested and it answers a single visitor as fast as many managed plans.
For a store, a membership site, or any site where a busy hour matters, I would skip shared hosting and pick a plan with CPU of its own: ScalaHosting's Entry Cloud, which held 58ms with 100 users, or a Cloudways server if I wanted to choose the cloud and run several sites. I would not buy a managed WordPress plan on the name alone; two of the five we tested were slower under load than a good shared plan.
