Subject: [dpdk-dev] [PATCH 0/5] Fixes and enhancements for Tx path in Virtio PMD
Date: Tue, 19 Feb 2019 18:59:46 +0800 [thread overview]
Message-ID: <20190219105951.31046-1-tiwei.bie@intel.com> (raw)
Below is a quick (unofficial) performance test (macfwd loop, 64B)
for the packed ring optimizations in this series on an Intel(R)
Xeon(R) Gold 6140 CPU @ 2.30GHz platform:
w/o this series:
packed ring normal/in-order: ~10.4 Mpps
w/ this series:
packed ring normal: ~10.9 Mpps
packed ring in-order: ~11.3 Mpps
In the test, we need to make sure that the vhost side is fast enough.
So 4 forwarding cores are used in vhost side, and 1 forwarding core is
used in virtio side.
vhost side:
./x86_64-native-linuxapp-gcc/app/testpmd \
-l 13,14,15,16,17 \
--socket-mem 1024,0 \
--file-prefix=vhost \
--vdev=net_vhost0,iface=/tmp/vhost0,queues=4 \
-- \
--forward-mode=mac \
-i \
--rxq=4 \
--txq=4 \
--nb-cores 4
virtio side:
./x86_64-native-linuxapp-gcc/app/testpmd \
-l 8,9,10,11,12 \
--socket-mem 1024,0 \
--single-file-segments \
--file-prefix=virtio-user \
--vdev=virtio_user0,path=/tmp/vhost0,queues=4,in_order=1,packed_vq=1 \
-- \
--forward-mode=mac \
-i \
--rxq=4 \
--txq=4 \
--nb-cores 1
