LoL

Sorry Wilson, for serving you more than you asked for :)
Its not really needed, just something I do :) As I said, you
should read about schedtools...

also:
$ man sched_setscheduler

 or

http://linux.die.net/man/2/sched_setscheduler

I just use it cuz I dedicate one cpu to snort...
All default other processes uses SCHED_OTHER and
they also start with an affinity that allows the
processes to run on all CPUS, and in this case,
leave the one that snort uses alone :)


Sorry again for the overload :)
