I can use pbind to bind snort to a processor but that won't help. Even
without pbind, it can utilize only one CPU and after binding it with pbind,
it would be only using one CPU. So no gain :)
whoa!!!!! I still did pbind and guess what? After binding snort to CPU-2, it
goes upto 80-90% usage (mpstat 5) and if i unbind it then the load seems to
get split, mpstat shows both processors getting loads between 30-60% (one
20%, the other 60% and various other combinations).
Whatever, pbind doesn't look like a good idea :)
