What is a good website response time?

Response time is how long a server takes to answer a request. As a rule of thumb, under 200 ms is fast, 200-500 ms is fine and anything over a second makes pages feel slow and can hurt search rankings. This checker measures the time from an independent server.

How to test a website's response time

Enter the domain in the box above.
Click Check Speed.
Note the response time; run it a few times, as a single slow result can be a one-off.
If it is consistently slow, look at server caching, a CDN, or a faster hosting plan.

JustChecker tracks response time trends over time and alerts you when performance degrades.

Frequently Asked Questions

Under about half a second is good; under 200 ms is excellent. Consistently over 1.5 seconds usually points to slow hosting, missing page caching or heavy database queries.

Server load, caching and network routes vary from moment to moment. Run it a few times and look at the typical value rather than a single result.

Turn on page caching, use a current PHP version, remove slow plugins and choose hosting with fast servers. A CDN helps visitors far from your server.
