For historical reason, we use Linux-2.6.18. Our company have several
products with CPU Xen, P4, or i7. Some of them are SMP, Multi-Core and
Multi-Threaded. We use the similar mechanism like dynamic weighted
RPS. The total throughput is increased nearly linear with the number
of the worker threads(one worker thread per CPU).
