Hi, I'm using Fedora 7 with the latest XEN kernel and I did some network benchmarks with iperf 2.02 and NETIO 1.26. The HVM domain uses 2 vcpus and it is the only DomU on this machine. I was interested in the network performance of a HVM domain in which Windows XP runs. At first I tested the TCP throughput which was relatively low, compared to a non emulated network device. ------------------------------------------------------------ Client connecting to 192.168.1.222, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.1.122 port 43748 connected with 192.168.1.222 port 5001 [ 3] 0.0- 1.0 sec 3.06 MBytes 25.7 Mbits/sec ... [ 3] 0.0-60.0 sec 177 MBytes 24.8 Mbits/sec After that I tested UDP performance and noticed a high package loss, but only in one direction. When DomainU is sending data to Domain0 all packages are received.In the other direction many packages are getting lost. ( When DomU is receiving data. ) C:\Program Files\iperf-2.0.2\bin>iperf -u -c 192.168.1.122 -r -L 22222 -i 0.5 -b 10m ------------------------------------------------------------ Server listening on UDP port 22222 Receiving 1470 byte datagrams UDP buffer size: 8.00 KByte (default) ------------------------------------------------------------ ------------------------------------------------------------ Client connecting to 192.168.1.122, UDP port 5001 Sending 1470 byte datagrams UDP buffer size: 8.00 KByte (default) ------------------------------------------------------------ [ 4] local 192.168.1.222 port 1170 connected with 192.168.1.122 port 5001 [ 4] 0.0- 0.5 sec 590 KBytes 9.67 Mbits/sec ...
