I'm currently configuring a web hosting server (Ubuntu 16, Apache 2.4, 8GB RAM, 6 Core CPU) with about 20 Wordpress and Magento 1.9.X/2.2.X sites and would like to optimize it for speed with Apache's mod_cache_disk.
But I'm not sure if there are any benefits or possible side effects of using mod_cache_disk with Magento.
I noticed some side effects for the Wordpress sites, for example the browser shows a page which isn't requested, but for Magento I'm not seeing any issues at the moment.
The current Magento vhosts/htaccess file has this caching configuration:
CacheQuickHandler off CacheLock on CacheLockPath /tmp/mod_cache-lock CacheLockMaxAge 5 CacheIgnoreHeaders Set-Cookie <Location /> CacheEnable disk CacheHeader on CacheDefaultExpire 600 CacheMaxExpire 86400 CacheLastModifiedFactor 0.5 </Location>
My questions are:
- are there any benefits of using Apache's disk cache with Magento 1.9.X or 2.2.X or is this counterproductive because of Magento's native caching system?
- are there any possible issues to watch out for if using this combination?
Also any general tips and experiences regarding this, would be appreciated.
Btw, I know that the recommended performance optimization for Magento is (in short) Nginx, Varnish, Redis, Memcached, but I currently don't have the knowledge nor the resources to configure this (although I am enthusiastic to do it one day).
