Hi,
I'm doing some test on a network 10 gb nics and xen
with version 3.1 i'm measuring 2.5 gb/sec from domU to an external physical 
machine with iperf.
switching to 3.2 has reduced the measured performance to 40-50 Mb/sec.

did anything change in the network interface?

can someone help me?

thanks
