Why am i getting this logging message?


#1

Hey everyone… here’s a multi-part question

  1. When I install WP with --wpfc option…
  • WHy is W3TC plugin installed? Does this need to be active for nginx cache to work?
  • When I check phpinfo(), i see that memcache is installed. Same question as #1
  • I want to run PHP7 + opcache… phpinfo states “Zend Engine v3.0.0… Zend OPcache v7.0.14-2+deb.sury.org~xenial+1”… does this mean it’s correctly stated?
  1. I am confused as to different caching layers. It is my understanding that to improve the performance of WP, there are these layers
  • CDN (which I am using cloudflare)
  • php7 cache (converting php to binaries)
  • database cache (which i thought redis / memcache is suppose to be)
  • browser cache (which i thought nginx cache is supposed to be)

If I am not using nginx cache, do I even need to manually set these as I see them in W3TC plugin settings?

I ask because during the WP installation, i get this message:

Page Cache: Disable Database Cache: Memcached Object Cache: Memcached Browser Cache: Disable

AM I supposed to ignore these messages?

PS: w3tc is great but it’s got WAY too many options for most users
