Hello, I did some network benchmarking with iperf. I have the dom0 and one domain where the vpn software OpenVpn is running. I want to measure the bandwidth of the vpn. The problem is that I get a bandwidth of 90Mbit/s on a 1Gbit/s connection. On a "normal" system I get a bandwidth of 110MBit/s. The bottleneck there is the cpu. On Xen the CPU is still idle (95% in dom0 and 45% in domU). At the moment I have only one domU. I think the cpu is the bottleneck under Xen, too. Is there cpu load which I can''t see with "top"? Is there a possibility to get the whole cpu load over all domains? Has anybody experiences with benchmarking the cpu load of the whole system? Thank you.
