70. vhost/virtio pvp multi-paths performance test plan¶

Benchmark PVP multi-paths performance with 9 tx/rx paths. Includes mergeable, non-mergeable, vector_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 path. Give 1 core for vhost and virtio respectively.

70.1. Test flow¶

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

70.2. Test Case 1: pvp test with virtio 1.1 mergeable path¶

Bind one port to igb_uio, then launch vhost by below command:

rm -rf vhost-net*
./testpmd -n 4 -l 2-3  --socket-mem 1024,1024 --legacy-mem \
--file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1,client=0' \
-- -i --nb-cores=1 --txd=1024 --rxd=1024
testpmd>set fwd mac
testpmd>start

Launch virtio-user by below command:

./testpmd -n 4 -l 5-6 --socket-mem 1024,1024 \
