The KVM website states: "VhostNet <http://www.linux-kvm.org/page/VhostNet> provides better latency (10% less than e1000 on my system) and greater throughput (8x the normal virtio, around 7~8 Gigabits/sec here) for network. "
I did look trough the mailing list but couldn't find information on the test configuration for the performance numbers. It would be helpful if someone from the kvm/qemu team provides details on, or a pointer to the location that has vhost perf numbers- (1) What was the VCPU configuration for this - single core, multiple cores?, memory (2) Details of the test - netperf , TCP/UDP, packet size Thanks Rukhsana
