I am looking for information on how to increase the speed and performance of my server (cento 7) I want my websites to run smoother and faster. Is this being discussed in the documentation?
ISPConfig itself has not much influence on the speed as it is not involved in processing http and php requests on a server. To get the most of the server hardware, you can start with these steps: 1) Use nginx instead of apache as web server. 2) Use a fast php mode (php-fpm). 3) Use PHP 7 for this website, it is much faster then php 5. 4) Install a PHP cache (e.g. opcache) and use caching extensions for your CMS. 5) Optimize MySQL settings and use mysqltuner to find the best settings for your hardware resources.
what should I be doing in the server side? If I change this FcgidMaxRequestLen the site loads faster..
one problem that I'm having is when I upload a video in wordpress ( 15MB) I get a HTTP Error I did change the max upload file size to 25MB but still having the problem
