I'm using the faster venet device for several OpenVZ nodes and have been evaluating the network performance using netperf. I'm using kernel 2.6.16-1.2133_FC5.026test015smp with gigabit ethernet on all nodes. What I've found is that the host machines are able to get near-native throughput (around 940 Mbit/s); however, VPS nodes max out around 300 Mbit/s. Xen, on the other hand, is able to achieve network performance similar to native speeds. Is there a configurable option that I'm missing that can improve network performance? I'm getting no failures reported within /proc/user_beancounters.
Any thoughts?
best regards,
JP
