Milestone
It was pointed to us by a partner that our installed Moodle config might be improved for optimized performance in relation to the shared file server directory (
/moodle
on Gluster or NFS). It was also pointed that these are all available in theconfig-dist.php
that's distributed with Moodle. Therefore, we should evaluate whether these are applicable to our architecture and incorporate anything that can improve performance. Here are the partner's verbatim:First, here are the alternative configurations for getting session data off the gluster:
(Note from @hosungsmsft: We do configure redis as the session handler when redis is chosen, but we are not configuring database as the session handler when redis is not chosen. We should evaluate if database session handler is better when redis is not chosen and make it default in that case)
Next, at the very least the localcachedir should be somewhere fast and local - not on the gluster.
I'm not sure whether you need to set the preventfilelocking flag.
(Note from @hosungsmsft: We should evaluate the localcachedir option in general and the preventfilelocking option for our NFS option)
I'm not sure about the impact of this next one but reading the description I would expect to use a local directory and not a gluster directory
(Note from @hosungsmsft: Not sure if this can be applied to our architecture. Need research)
