the short answer is we really don't know. 

you could look at 

http://www.linuxvirtualserver.org/Joseph.Mack/HOWTO/LVS-HOWTO_1.0-5.html#ss5.2

for information on why we don't know in your case.

A longer answer would be the this seems a reasonable setup 
based on other anecdotal statements on this mailing list.

you have the PCI bus to consider too. I would expect that since LVS is largely
kernel code, that running SMP with 2.4.x kernels will give you more throughput.
