Next steps are as Robert suggests, the USE method. ixgbe uses 8 rings by default, so it will spread nicely. By contrast, if e1000g#0 was consuming 100% of a CPU, then that might be an issue. At this point, I think you can eliminate CPU utilization by NIC and network saturation as the bottleneck. — richard > > With 79 running (but idle) KVM servers there is only 23 Mbps bandwidth > according to iperf.
