Several times, the hosting company for my website (GoDaddy) has told me that a caching plugin on my Wordpress based website is unnecessary, because I am using Cloudflare as a CDN and a cache plugin like W3 Total Cache or WP Super Cache could cause conflicts. My priority is optimizing my website so that it can perform as best it can, so I am inquiring to know if this is actually true.
I’ve had issues with W3 Total Cache (maximizing CPU usage and I/O usage on my website when manually purging the cache, consistently leading to a temporary hang) and WP Super Cache (general problems). I don’t know if those issues are due to a conflict with Cloudflare, or if there are certain settings I’m overlooking.
My website currently uses the Autoptimize plugin, is running on Cloudflare, and there is an ad optimization platform which has its own caching app.
