I'm also quite interested by small files performances optimization, but
I'm a bit confused about the best option between 3.6/3.7.
Ben Turner was saying that 3.6 might give the best performances:
http://www.gluster.org/pipermail/gluster-users/2015-September/023733.html
What kind of gain is expected (with consistent-metadata) if this
regression is solved?
I tried 3.6.5 (last version for debian jessie), and it's a bit better
than 3.7.4 but not by much (10-15%).
I was also wondering if there is recommendations for the underlying file
system of the bricks (xfs, ext4, tuning...).

If you're not already on Glusterfs 3.7.x i would recommend an update

Hi,
There are quite a few tuning parameters for Gluster (as seen in
Gluster
volume XYZ get all), but I didn't find much documentation on those.
Some people do seem to set at least some of them, so the knowledge
must
be somewhere...
Is there a good source of information to understand what they mean,
and
recommendation on how to set them to get a good small file
performance?
Basically what I'm trying to optimize is for svn operations (e.g. svn
checkout, or svn branch) on a replicated 2 x 1 volume (hosted on 2
VMs,
16GB ram, 4 cores each, 10Gb/s network tested at full speed), using a
NFS mount which appears much faster than fuse in this case (but still
much slower than when served by a normal NFS server).
Any recommendation for such a setup?
Thanks,
Thibault.
