Issue Gateway timeout

[cits]

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

Plesk Obsidian Web Admin Se Edition Version 18.0.61 Update #5

I am using an aws cloud instance with latest plesk obsidian to run some wordpress websites. One of the website has about 30gb of contents. Currently I am getting was Gateway timeout from nginx. After searching for some fixes, found Issue - Prestashop 8 : very slow and error "504 Gateway Time-out - Nginx" and I stopped nginx. For every restart of apache, the site runs for some minutes and then get the gateway timeout error

Probably too many requests are sent to the web server so that it is getting slower and slower with every new request. You can
a) Check the access_log of the web server whether bad bots are hitting the website. Block them.
b) Check the number of PHP-FPM instances that are created (ps aux | grep php-fpm). If there are many for your website, but (a) has already been ruled out, reduce the max script runtime in the PHP settings drastically (e.g. to only 5 seconds), as there seem to be long running scripts in your website.
c) Make sure that your shop can access resources fast. If the shop has to wait on resources, many additional PHP-FPM instances can build-up which will again result in the webserver to become unresponsive. Does the shop wait on responses from external sources for example?

After following the instructions from https://support.plesk.com/hc/en-us/...t-for-var-www-cgi-bin-cgi-wrapper-cgi-wrapper, Gateway timeout has been escalated. But now the website is performing very slow;

Still the same causes as mentioned above. Too many too long running processes.
