You didn't provide your current config or what version you are running
but you may find this useful:

I'd be interested to hear what happens if you repeat your tests with
some performance settings changed. I will be configuring Gluster in an
HPC cluster with ~83 million files and I'm going to run into the 'lots
of small files on replica sucks' problem.
Also, here's my testing but it was on a very limited network (stuck on a
100Mb switch):

I have set up my first 2 node gluster with 1 GbE for testing.
Thanks to very good documentation, it was easy.
My aim is to use gluster for LXC VM replication.
Write performance is a critical issue for me.
Test case 1: copying 22000 files with 1 GB totally
local disc/filesystem: 47 MB/s
NFS3: 13 MB/s
glusterfs: 4 MB/s
Test case 2: writing one file with 1 GB
local disc/filesystem: 123 MB/s
NFS3: 95 MB/s
glusterfs: 67 MB/s
Especially the result of test case 1 is very disappointing. Is there a way
of tuning it up?
