What is Site Speed Test?

TTFB (Time To First Byte) measures how long it takes for a server to start sending the first byte of a response after a request is made. It's one of the most important metrics for site speed, reflecting server processing time, database queries, and backend performance. Our tool measures TTFB, total response time, and download size, giving you a clear picture of a site's server-side performance.
