Hi, I'm running OVS-1.4 release on a low frequency x86 machine. I see that performance doesn't seem to scale linearly from 1 to 2 to 4 cores.
I have three PC setup: PC1 is generating netperf traffic, PC2 runs OVS, PC3 is terminating traffic. OVS is bridging between two ethernet ports. The datapath uses RCU locking mechanism which is quite efficient. What could be other areas where there is contention when running OVS on multi-core machine. Thank you, Marty! PS: Would upgrading to a later version help?
