[Gluster-users] talk about enhance gluster nfs performance

[Matthew McKeen]

I tried to parse your English, as it seems not to be your first
language, but I've grokked that you are basically having issues with
NFS performance.

One thing I've tried is to run multiple NFS daemons per server, this
can easily be done with CTDB, multiple IP addresses per server, and
one NFS daemon for each IP address.

The hard part of this is to override the default NFS daemon started by
glusterd and manage the daemons outside of glusterd.  I've used runit
for this, but any decent init system should work.

I've seen this scale NFS performance significantly and enable much
better CPU utilization in a high IOP environment.

Besides this work around, I would also be interested in the progress
on epool.  Have NFS daemons limited to processing events on a single
thread is truly a bottleneck in high IOP environments.


Thanks and best of luck!
