[ovs-discuss] assigning number of cores to datapath

[Hardik Soni]

Okay. I understand that switching doesnt take much time. 
But what about flowtable update in kernel datapath from userspace.

I was not elaborate in my question, I have following scenario.
I want to run 2 ovs-switch instances on single machine. But, they should not affect each other's performance.
So, I thought if I can assign # of physical cores to them..
I am using Open Vswitch with kernel module.

Thanks,
Hardik Soni
