126. vhost/virtio pvp multi-paths vhost 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 virtio and 1 core for vhost, set io fwd at virtio side to lower the virtio workload.
