hello~
openvswitch.org/support/ovscon2014/18/1600-ovs_perf.pptx
<OpenVswitch Performance measurements & analysis> written by Madhu Challa,
shows some tests that datapath forwarding performance is lower than ovs+dpdk.
STANDARD-OVS DPDK-OVS LINUX-BRIDGE
Gbits / sec 1.159 9.9 1.04
Mpps 1.72 14.85 1.55
1) What is the main reason for the lower performance of datapath compared with
ovs+dpdk?
2) If we create some kthreads for datapath to poll the NIC??and running
datapath in the kthreads, how about the performance compared with ovs+dpdk?
That should not be lower than ovs+dpdk in theory, I guess._______________________________________________
