I'm trying to implement a clustered environment on AWS
On the benchmark section, I get all greens except for the temp files section, in which I access the NFS share and thus, get a really slow performance.
According to the Cluster installation guidelines, the temp dir MUST be shared between the hosts https://docs.moodle.org/310/en/Server_cluster#.24CFG-.3Etempdir
However, setting the tempdir to tmpfs on each host boosts the benchmark numbers up a lot.
My question is: What I used session stickyness with this local temp caching solution? Wouldn't I bypass the necessity to share the temp folders?
Is there any other way to share the temp folders in a more efficient way?
Any NFS mount or tunning advice? There's lots of info around the web but most of them are either outdated or just plain don't work.
