Gluster users - Apr 2015 - talk about enhance gluster nfs performance

Hi all,
     How To enhance the gluster performance of NFS, when EC, the network
transmission time long processing time, effect of NFS IOPS;
     In our tests, each EC IO needs 1ms(Gigabit Network), NFS can only handle
1000 IOPs ;NFS protocol message and the process in the same process,The process
will block the NFS protocol message received;
     Why not the received nfs message packet and nfs protocol processing process
isolation Or NFS multi thread;
     By the way, the progress of gluster epool multithread, if use epool
multithread ,can solve the problem gluster nfs performance.?
Best regards
 

??????:cluster nfs

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!
