Issue Very high TTFB when selecting FPM Apache vs FCGI :(

Have you tried to enable keep-alive requests?

TTFB for site is too high in Plesk. What can be done to improve it?

To get TTFB value we need to subtract the "Start Transfer" value from the "Pre-Transfer" value here. In both cases, TTFB is less than 1sec and it is not so bad, actually.

Are you taking advantage of OPcache? OPcache can behave strangely with inefficient or error-ridden code which in some scenarios could possibly negate its benefits.

Thanks for your question. opcache.enable was set on so far. I disabled it but it didn't make it any faster. Still FCGI also had it enabled and it runs much faster?
Shouldn't FPM be faster in general?

Sorry, I really don't have the time for the entire screencast, intro and all, and it's likely that not many forum members will look at it. Do consider a different approach.

Are the two test sites from the first post still active?
