[Gluster-users] Speed of glusterfs

we're currently testing glusterfs but getting a real slow connection with it.
I setup a environment with 2 replicated storage servers. Both machines and the
client are connected by 1 Gbit, but if I copy a 2.5 GB file from the client to
the volumen mounted with glusterfs protocol, I never get more than 35-40 MB/sec.
On the two storage I also run a NFS server. If I copy the same file from the
client to one storage by NFS (the NFS server that was shipped with RHEL6), I
get never less than 90-95 MB/sec. So the network/HDDs are possible to provide
Is there a change to get glusterfs to about the same speed? And why is it so
slow? Does the glusterfs send the data directly to both storages? This would
explain why it is so slow. But is there a change then to send the data just to
one server and this one replicates it (over a second NIC) to the second one)?
