I need to retest my set up with multi-threads vhost. My previous set up applies to single thread vhost. The single stream netperf/netserver set up, for example, if we have two quad-cores sockets to get the consistent 9.4Gb/s BW:
socket 1: cpu0: netperf/netserver cpu1: ixgbe 10GbE NIC IRQ cpu2: I/O thread cpu3: vhost thread
socket 2: cpu0: QEMU VCPU0 cpu1: QEMU VCPU1 cpu2: cpu3:
Thanks Shirley
