linux scheduling

My scheduling question is:
Based on my (limited) experience with freebsd it seems that thier
scheduling system allows priority to console applications. This can be
seen on one of the dual boot machines we have set up. If the system is
under heavy load, It appears as though the FreeBSD os will give the
console interactive apps priority over, say, a compilation in the
background. The same situation results in "mouse-stutter" and long
delays in a cursor response after a request is submitted. The 4.4 BSD
redbook confirms that the allow priority to interactive apps. (pg. 79). Is
there some way to implement this, or is it purely a tuning issue.
This could (possibly) be useful in thwarting a dos attack. It would
certainly makes administering a box more fun when its responsive(even
under heavy load).

Thanks for your time,

Matt
