How i could reduce Time for the first byte?

Answer 1

Nobody can give you a detailed answer without you showing the code responsible for generating the content of the site - because that's where the delay is.

However, since the site is using php, you are most likely using output buffering

Given that's the case, the following code will give a TTFB of (network latency +) 2s:

Whereas this will give you a TTFB of (network latency +) 0s:

The time to load the whole page is the same in both cases - only where the delay is changes. If you are specifically focussed on reducing TTFB (why), that should give you enough information to investigate further.

IMPORTANT: There are a lot of frontend changes you should make before focussing on TTFB.
