I have a questions about smp and if LVS is smp aware. I have a Dell 1650
with dual 1.1Ghz processors, dual 1000BaseT Ethernet, with 2.4.20 compiled
as an smp and with the lvs sources compiled in. I have it set up as a one
nic one network DR unit with wrr and it is working very nicely. It is
pushing about 50Mb at peek and is only using about 15% on average of the
processing power when doing a vmstat. Now here's the question when doing a
vmstat the numbers look like this:

this is a snapshot when we are doing about 30Mb.
now if I look at top I get.

When doing more traffic the load on cpu0 increases and nothing is happing on
cpu1.
My question is why am I not seeing this processor usage distributed over
both processors. I know that on a Sun box the network card is stuck to a
single processor and will not use the other processors.

Oh and just for those of you what want to know here is my ipvsadm output.
