Adding SMP into the mix makes thing more complicated, and you should consider
other alternatives first before spending money on hardware that might not help.

vmstat -i output would be useful to know, along with what your machine is
doing-- is it routing traffic, running a firewall (if so, which), etc.

You might take a look at "man polling" and see whether enabling that improves
your situation.
