127. vhost/virtio pvp multi-paths virtio single core test plan¶

Benchmark PVP virtio single core performance with 10 tx/rx paths. Includes mergeable, non-mergeable, vectorized_rx, inorder mergeable, inorder non-mergeable, virtio 1.1 mergeable, virtio 1.1 non-mergeable，virtio 1.1 inorder mergeable, virtio 1.1 inorder non-mergeable, virtio1.1 vectorized path. Give 2 cores for vhost and 1 core for virtio, set io fwd at vhost side to lower the vhost workload.

127.1. Test flow¶

TG –> NIC –> Vhost –> Virtio–> Vhost –> NIC –> TG

127.2. Test Case 1: virtio single core performance test with virtio 1.1 mergeable path¶
