On an Ubuntu 18.04 Machine With Apache2,
I'm using mod_pagespeed with default settings except 2 options.
I've installed memcached and enabled the following in "/etc/apache2/mods-available/pagespeed.conf" by removing "#"
- ModPagespeedMemcachedServers localhost:11211
- ModPagespeedCreateSharedMemoryMetadataCache "/var/cache/mod_pagespeed/" 51200
My question is, do I still need a plugin e.g. Autoptimize, W3TC, WP Super Cache and etc. to cache, minify etc. etc.?
Any help would be highly appreciated. Thanks!
Cache Plugins in general: Like alway the world is divided into those who love them and those who curse them.
Ask yourself, if you should use them? Is there any benefit for your page?
That depends on the page. Noone can decide that for you.
Helpful are some seo tools - e.g. Google PageSpeed.
Disable all cache plugins and check your page speed. Sometimes a page is blown up with many plugins generating tons of code (sad to say not rare duplicated and included twice or more times).
Check your plugins and also check your page (frontend) with the developer tools. Mostly there are many loads you do not really need.
You mentioned
You can do that by yourself (e.g. with Brackets and the minifier plugin or online on mifier pages).
Even the includes for most of the plugins can be minified.
The intention:
Check your page and optimize it. If it not really needs the cache plugins for some functionallity or an high increase of page speed - why use them?
