I would like to share experience about filesystem on Moodle 3.7.x in cluster.
We've a score near 40 for Writing file performance.
Your Moodle data is on a share we access it using NFS and the filesystem itself is CEPH.
We've six computers behind a load balancer. (16 cores x64 intel, 24gb ram) it's on Debian 9, Apache2, we use Memcached for sessions and for the muc.
I've some questions :
1. Could you please share your performance on your Moodle if they using share for Moodle data and Moodle is on clustering ?
2. Is someone have already change from NFS to GlusterNFS (or else) and had a good performance gain ?
Your Moodle have an overall good performance more 35000 unique visit every days and +/- 500 concurent users.
The bad performance happen when we've to restore courses and backup it.
Any advice are welcome, I hope I was clear enough. I've read the Moodle advice on performance it's the reason I ask for the GlusterNFS but we also wish to have also feedback from others about their infrastructure and performances.
