Resolved Plesk Slow Connecting and SSL Time

[Aude]

Hello,

i'm in trouble. When i test pages speed with GtMetrix (and other).
my connecting time is near 400ms and ssl 300ms. when i check my concurrent they are always <100ms.

My server is 16cpu 32GoRam. No problem on this side.

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

So not a network issue

Only one website with prestashop, opcache active, php fpm , pm.max_children = 40
Same probleme with static content


Any ideas to investigate ?

Thanks

In order to determine the real TTFB try to test a request for a static file (an image). Do not test against the website, because there the .php scripts will execute and there can be hundreds of delays when rendering the site.

And what exactly was the result of that test?
