[Gluster-users] performance tuning?

[Ulli Horlacher]

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?
