xen全虚拟化网络吞吐测试 -
摘自:http://apps.hi.baidu.com/share/detail/23999810 <待验证>测试工具: netperf
网卡：百兆网卡
测试命令：netperf -H xxx.xxx.xxx.xxx
虚拟化情况下dom0:
# netperf -H 192.168.203.37
TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.203.37 (192.168.203.37) port 0 AF_INET
Recv Send Send
Socket SocketMessageElapsed
Size Size Size Time Throughput
bytesbytes bytes secs. 10^6bits/sec
873801638416384 10.11 94.13
可以看出dom0中网络传输速率可以达到94.13M/s
虚拟化情况下hvm domU:
# netperf -H 192.168.203.37
TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.203.37 (192.168.203.37) port 0 AF_INET
Recv Send Send
Socket SocketMessageElapsed
Size Size Size Time Throughput
bytesbytes bytes secs. 10^6bits/sec
873801638416384 10.00 60.41
可以看出全虚拟化的domU其网络传输速率仅有60.41M/s
全虚拟化安装了pv driver之后hvm domU：
# netperf -H 192.168.203.37
TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.203.37 (192.168.203.37) port 0 AF_INET
Recv Send Send
Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec
87380 16384 16384 10.30 94.13
可以看出安装了pv driver之后全虚拟化的domU其网络传输速率可以达到94.13M/s，得到了大幅的提升
所谓的pv driver就是针对底层已有的xen虚拟化环境提供的接口，重新编写对应硬件的驱动，替换原有直接控制硬件的接口，实现速度的提升
