Well, that is all fine and well, and I really hate to sound like a brat, 
but it is not the system that is causing the lag time we're getting from 

We've changed NOTHING on the system.  The types and number of tasks 
running on the machine are the SAME.  The MOO's background tasks are the 
same.  We've ruled out everything except the moo server.  

The one change we DID make was installing FUP in extensions.c as oppossed 
to the typical files.c and hacking of various files for compiling.  We 
recently moved back to the "old" form of having files.c and not using 
extensions.c ... this DID cut back some of the lag.

I cannot think of anything else that could be causing this "sudden" 
sluggishness.  The machine is the same, the tasks are the same.  The only 
difference is the server version.  It is disconcerting that it looks like 
we have two choices: Grin and smile and hope it just goes away or lose a 
LOT of work in order to convince people it is indeed p4-5 that has caused 
this increase in CPU useage and thus extremely sluggish server.
