What Time to First Byte measures

TTFB measures how quickly visitors to your website receive a response from your server. The faster the better!

There's more to website speed than TTFB

Why web performance matters

TTFB and CDN Performance

Optimize TTFB with a Content Delivery Network

Check your CDN is working correctly

Use our TTFB tester to verify that responses are served from a location close to where the test is run.

Investigate cache statuses

View CDN and browser cache information

Global cache status can vary

Sometimes visitors in different locations can experience great differences in server response time. That's because different CDN edge nodes may or may not have a cached response. Especially less frequently accessed edge nodes are less likely to have the response in the CDN cache.

TTFB and page speed monitoring

Monitor website performance continuously

DebugBear can keep track of your page speed and Core Web Vitals over time. Track TTFB and other page load milestones to ensure your website is always fast.
