Hi, Roman,

I still want to make sure if you are running the multi-threaded click on
multi-core Xeon or multiple CPUs. I got much improvements on mutple CPUs,
but not on a dual-core Xeon. I'll very appreciate if you can provide some
data on the numbers of forwarding 64B size packets on 1-thread and 2-thread
on a dual core Xeon CPU.  Thanks.

Regards,
Qinghua(Kevin) Ye
