you can try and run an smp kernel on even one cpu.
it will make use of the ioapic(s) if present that
should make better interrupts processing. also depending
on your hw some hw supports interrupts coalescing
such as em(4) for example that you can play w/ #defines
in the driver to make less interrupts and high pkt/int...
