I miss the code in V1 as followings.
Disable notifications.
virtqueue[i]->used->flags = VRING_USED_F_NO_NOTIFY;
I will add it in next version. It can increase throughput sharply for vhostpci/ virtio PMD loopback test.
The similar performance result can be seen compared to vhost user/virtio PMD loopback test after disabling notifications.
thanks
Zhiyong
