Optimizing TTFB (Time to First Byte)

Time to First Byte (TTFB) is the exact amount of time it takes for a user's browser to receive the very first byte of data from your server after requesting a page.

The Culprits of Slow TTFB

High TTFB is rarely a network issue; it is almost always an application issue. Unoptimized database queries, bloated PHP code, and lack of page caching force the server to "think" for seconds before responding.

The Solution

Implement Full Page Caching. By generating the HTML once and storing it in memory, the server skips the PHP execution entirely on subsequent visits, dropping TTFB to near zero.
