I'm running two windows 2012 server on a Suse xen hypervisor.

I've tested network performance with IPERF
I've got
0.0-10.1 sec  56.8 MBytes  47.3 Mbits/sec
without GPL PLV drivers
 0.0-10.0 sec  3.20 GBytes  2.74 Gbits/sec
with GPL PLV drivers

I've noticed a strange thing GPL PLV drivers. When they are installed, task manager of windows show a correct number for send packets but received packets always stay at 0.
Is there an explanation for this ?

Second problem is that I have a backup agent on the windows server who talk to the master backup which is on the suse server. Every time i run the backup, after a while, the connection is lost with "Client session terminated (repair failed) with socket error (Erreur 51: Échec du socket)"

Is anyone has the same problem ?
