I'm curious. A lot of network cards support offloaded vxlan traffic these days so the processor isn't doing much work. Is this issue really a problem?

Thanks,

Subject: [Neutron] NUMA aware VxLAN

Hi,

 

Existing neutron ML2 support one VxLAN for tenant network. In NUMA case, VM 0 can be created in node 0 and VM 1 can be created in node 1 and VxLAN is in node 0.

 

VM1 need to cross node, which cause some performance downgrade. Does someone have this performance issue? Does Neutron community have plan to enhance it?

Thanks,
