Time to First Byte (TTFB) is the time it takes from the very first request made to the server to the first response the browser receives. It determines the overall performance that the user will experience while browsing your website. If the first request is slow, the rest of the experience will also feel sluggish. A user expects things to happen almost instantaneously which is only possible with a fast TTFB.
Servebolt reduces TTFB by reducing unnecessary database requests, optimising PHP code processing, using smart HTML caching, and many other optimizations on the server level.
