Re: CloudFlare - huge difference in caching performance between WP and J!
Posted 1 year 5 months ago
My best guess is that CF just caches WordPress sites better because they've put more time into the nuances of WordPress since it's a more widely used platform. By your own numbers a significant larger portion of your WP site is being cached compared to Joomla ~ 25% compared to 85%
Joomla has it's own built-in cache whereas WordPress does not... though there are many 3rd party plugins for WordPress that do an excellent job. I would hope/assume CF is serving the cached files... but you'd need to dig into that... if not, perhaps turning off the caching in Joomla would actually help.
I like JCH Optimize for local caching on Joomla and WordPress Fastest Cache for the same on WP
