I have been searching for the reason why the Response to Server (TTFB) has some major delays on:
[login to view URL]!/cu9yoV/[login to view URL]
without finding the real reason. It resides on a shared server which in fact is running with good hardware and the site is running PHP 7.1, APCu cache, Cloudflare, PrestaShop 1.6.1.18 platform configured with the best speed optimization setting in the backend
As seen on the metrix test the site requests are loading within seconds, but the first http/https request to the server can delay the site all from 3 seconds to 20 seconds. If I do a re-test it will go down to 2-5 seconds, but if I haven't accessed the site 30 min and up, issues will arise again with high load time.
How do I find the culprit which is delaying the TTFB? The hosting company with all their resources for testing/monitoring haven't provided me with a clear answer.

This issue can be related to other Websites on the server.
Because, You are on a shared server , So, Load will depends on other accounts also,
I always prefer to use a dedicated server.
After that Enabling Google_page_speed module will help.

Hi, vivek8labs here,
TTFB could be related to caching. there must be something which re validate the cache and it take time to cache again which make the page load slower in one first request and when you make second request there is cache available and it server the page instantly.
Thanks
Hi
Try me on this.
I suppose this is database related issue: some slow query is cached but after a while the cach dropped.
I can try to find that query(ies) in test and production environment.
All the best
