Hi Matan, In our daily regression test, we found this patch set will decrease virtio performance and causes virtio interrupt not working properly in multi queue scenarios. Could you help to take a look? Details in Bugzilla https://bugs.dpdk.org/show_bug.cgi?id=507, btw, pls use low qemu version(qemu<4.1) to reproduce the second issue since the case blocked by one qemu bug with high qemu version.
