I have been stuck by this problem for the whole week.
We just did a simple experiment to test the network performance in xen use the benchmark--iperf. Our NIC is Gigabit, and we got exactly correct data in hostOS--fedoral core 8 without xen running, the bandwidth of the network was 931Mbps. But the problem is, when we start guest OS--fedoral core 8, and running iperf on it, we got data only 48Mbps! The data is same as that used 100M NIC.
Can you tell me, are there some restrictions in xen when use Gigabit NIC? Or should we do some configuration to use it?
Maybe I miss some configurations or make some mistakens.
Thanks for looking.
