98. vhost/virtio pvp performance test plan

Benchmark PVP performance with split ring mergeable path and packed ring mergeable path. For basic pvp test,give 1 core for vhost and virtio respectively. For virtio single core performance test,give 2 cores for vhost and 1 core for virtio, set io fwd at vhost side to lower the vhost workload. For vhost single core performance test,give 2 cores for virtio and 1 core for vhost, set io fwd at virtio side to lower the virtio workload.

98.1. Test flow

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

98.2. Test Case 1: pvp test with packed ring mergeable path

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

    rm -rf vhost-net*
    ./testpmd -n 4 -l 2-3  \
    --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
    
  2. Launch virtio-user by below command:

    ./testpmd -n 4 -l 5-6 \
    --no-pci --file-prefix=virtio \
    --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,packed_vq=1,mrg_rxbuf=1,in_order=0 \
    -- -i --tx-offloads=0x0 --enable-hw-vlan-strip --nb-cores=1 --txd=1024 --rxd=1024
    >set fwd mac
    >start
    
  3. Send packet with packet generator with different packet size,includes [64, 1518], check the throughput can get expected data with below command:

    testpmd>show port stats all
    

98.3. Test Case 2: virtio single core performance test with packed ring mergeable path
