[ovs-discuss] How to enable ovs-vswitchd to use more cores

Wed Mar 23 04:44:06 UTC 2016

Hi All,

Good Morning.

I am running OVS 2.4.90 on a VM (Ubuntu 12.04) with 8 Core and am testing
the performance by simulating insertion of several 1000s of flow per
second.  When I check the vswitchd CPU usage(using top) it shows 100% and
many of flow insertions fails.  Since the VM has 8 cores why the vswitchd
is not using more cores.

Please let me know how to configure OVS to using more cores.

Thanks,
Ravi
