What is TTFB?

TTFB stands for Time to First Byte. It is the time taken by the browser to receive the first byte of data from the server. A low TTFB value results in a better user experience. To ensure that a website has a low TTFB worldwide, our tool measures it from 40 different locations.

Testing the Right Way

This tool performs the TTFB test on a single resource at a time. This resource could be anything on the web such as an HTML Page, an image file, a font file, a CSS stylesheet, or a JavaScript file. This can help measure the response time of your origin server or CDN Provider across the globe. We recommend repeating the test a couple of times to obtain accurate results as this ensures that resource is cached and served from your CDN Provider's closest datacenter.
