Hi all,
Seems that I am seeing light in he tunnel!
I have done the below:
Added the option
/etc/glusterfs/glusterd.vol :
option rpc-auth-allow-insecure on
restarted glusterd
Then set the volume option:
gluster volume set vms server.allow-insecure on
Then disabled the option:
gluster volume se
I don't see any other bottleneck. CPUs are quite idle. Seems that the load
is mostly due to high latency on IO.
Reading further the gluster docs:

I see that I am missing the following

This is an incorrect way to test performance, for various reasons:
1. You are not using oflag=direct , thus not using DirectIO, but using
cache.
2. It's unrealistic - it
For a first idea I use:
dd if=/dev/zero of=testfile bs=1GB count=1
When testing on the gluster mount point using above command I hardly get
10MB/s. (On the same time the network traffic hardly reaches 100Mbit).
When testing our of the gluster (for example at /root) I get 600 - 700MB/s.
