Hello All,

I am wondering, what is consideration and performance impact if I setup a instance of 2 vcpu with hw_policy=dedicated, where both of vcpu pinning into both siblings of a core in single numa node. Or, does performance will better if vcpu pinning into single sibling in different core in single numa node?

Thank you.

Core 1 takes longer to access RAM of core 2 than its own RAM.

I found a slide presentation from Ian Jolliffe : "Nova Scheduler:Optimizing, Configuring And Deploying NFV VNF's On OpenStack".

More less, I think his slides answer my questions above.

thank you
