My website is really slow to load.

[Ch3ma]

Hello, after trying some solutions that I saw on the forum, one of my webpages still load in 20secs or more. At the moment I have no clue. Theres at least 3 more webpages hosted on the same server, and they work fine. I'm having this issue with one specific web. Any ideas? I attached my Real-Time Monitoring. Thanks in advanced.

looks like a PHP / MySQL site, and cloudflare are in front of lsws:
Server:cloudflare-nginx
Transfer-Encoding:chunked
Vary:Accept-Encoding
X-Powered-By: PHP/5.5.24
X-Turbo-Charged-By:LiteSpeed

in general, the bottle-neck is at php / mysql side. tips:
1. optimize php / mysql
this is the most important part.
2. enable opcache -- Zend OP cache or xcache
run ohdios in ProcessGroup mode : https://www.litespeedtech.com/products/litespeed-sapi/php/suexec-processgroup
this is best lsws can do and apache can't.
