Hi, I can't talk about performances on newer versions, but as of gluster 3.7 / 3.8, performances for small files (like a website) are pretty bad. It does work well though as long as you configure OPCache to keep everything in memory (bump the cache size and disable stat). As for storing a disk on gluster, it would work a lot better yes but that's not doable for a website, as you need all of your webservers to access the files at the same time. For that you'd have to use OCSF2 instead of ext4, and that defeats the purpose of using glusterfs in the first place I think. You could consider setting up your 3 servers as hypervisors (we are using proxmox in that configurating) and use gluster as your shared storage, then set up a VM on that cluster : that way you would have a highly available web server. That works very well, but that might be overkill for just one website. I'd go with what you are thinking of, it's simple to setup and with agressive OPCache settings it works fairly well ! You really don't want to forget disabling stat though. You'll have to restart PHP-FPM everytime you make a change to a php file, but it's worth it. One last thing, use a redis / memcache / whatever to store your application cache, I don't know joomla but if it's anything like prestashop / magento / wordpress, storing the cache on glusterfs will kill performances even more than forgetting to disable stat in OPCache.
