Here's the situation:  When a system is idle (win32, unix, or any other preemptive system), the client set at nice=0 (which 
will equal the maximum amount of niceness possible) WILL get all processor time IF the system is idle.  If, for whatever 
reason, you are set at nice=0 and losing speed, this is because some other program is running on your system, such as 
netscape/findfast/etc.  The real solution is not to set nice=2. but rather to find the other program and kill it (nicely, of 

I would not recommend that ANYONE use nice=2, as it will cause noticeable slowdown in some applications.  After all, 
we're out to prove how much we can do with idle cycles; the primary purpose of your computer is still to run the 
foreground applications you use as fast as possible.
