Pick the shape for where you will post it. The comparison strip keeps the nine regions in the same order, with its scale marked on the right.
How the test works
Nine test servers on five continents ask for your page at the same moment and time every step, the way a new visitor's browser would.
One visit from each region
Virginia, Oregon, Sao Paulo, London, Frankfurt, Mumbai, Singapore, Tokyo and Sydney each open a fresh connection to your site.
Every step timed
DNS lookup, connect, TLS handshake and server wait, until the first byte of your page arrives. The bar in each row shows where the time went.
A grade you can share
The average sets the grade. Download the report with or without our branding, or copy a link that opens the same result.
What your grade means
Server wait is the part your host controls: the time to build the page and start sending it. A page cache or a CDN that caches HTML moves a site up this scale fastest.
Questions
What is a good TTFB?
Google's web.dev guidance calls up to 800 ms good. For a site with a page cache, aim lower: under 200 ms on average earns an A here, and under 400 ms in the regions where your visitors live is a strong result.
Why is my result different from my browser's?
Your browser reuses connections it already opened, so a repeat visit skips most of what this test times. Every request here is a first visit: a fresh connection, a full TLS handshake and the page itself, which is what new readers and search engines get.
What does Answered from mean?
When a CDN serves your site, its response names the data center that answered, as an airport code like LHR for London or IAD for Washington. If a region is answered from far away, visitors there wait longer, even when the page is cached.
Does the test follow redirects?
Yes, up to three. The times shown are for the final page, and the notes under the table say how much the redirect added.
How is the grade worked out?
From the average TTFB across the regions that answered: A up to 200 ms, B up to 400 ms, C up to 600 ms, D up to 1,000 ms and F above that. The speed score runs from 100 at 100 ms to 0 at 1,500 ms.
Can I put my result on my own site?
Yes. Every test gets its own saved link that always shows the same result and the date it ran. Press Embed under your result to copy a small HTML card or an image badge that links to it, or download the report picture for a post.
How many tests can I run?
Ten an hour from one connection, so the test servers stay quick for everyone. Each result has its own link you can share.
Choosing a host?
We run these tests on every host we review, on our own WordPress sites, from the same regions.
