Thanks!

One more question, since CPU usage for LVS is so low will processor cache
affect it?

More processore cache is always a win.

 Can I expect a P4 w/1MB cache to outperform a P4 w/512KB (I'm
talking LVS performance only here)?

It depends on your traffic. Generally yes but with low volume traffic it might be the same since the required cached LVS conntrack entries fit into the cache lines just perfectly. I didn't even know that you could get P4 with only 512Kb of cache ;).

Tell us how much and what kind of traffic you expect and we can run the numbers.

Cheers,
