Help understanding cache options
By Blue
I have SimpleCache and System Cache enabled currently, but my performance page says Memcache, Redis, and Apache mod_cache are unavailable. I am using 3.3.13.
I see in the documentation that I could also do boot cache, X-Sendfile (I'm on Apache2), Composer Autoloader Optimization (2 ways), or a PHP code cache. Plus image caching.
How many cache methods am I supposed to use, as many as possible? Or which combination(s) are most effective? Should I start with Memcache and mod_cache and X-Sendfile or what?
Thanks!

Elgg simple/system cache and OPcache are required.
Any extended caching setup (Memcached\Redis) is one plus else for your site performance.
Ok, I have OPcache. So I will do SimpleCache, System Cache, Memcached, Redis, and mod_cache.
About about boot cache, X-Sendfile, Composer Autoloader Optimization, PHP code cache, image cache? They would each help also?
The documentation explains all about it.
We don't use Apache.
What is it?
Just Google on 'website performance', then learn and use developers' services.

Well I feel that the documentation just listed many, many options including PHP code cache, image cache, X-Sendfile, boot cache, Composer Autoloader Optimization. There was a short description to explain what they are, but it doesn't tell me which is best and if any cannot be used at the same time. Should I be trying to do all 5 in addition to already doing 5 (OPcache, SimpleCache, System Cache, Memcached, Redis, and mod_cache)?
Start with OPcache, SimpleCache, System Cache.
Perhaps, mod_cache for Apache.
Use CPU, memory metrics.
Is the site slow anyway?
Enable more caching services.
