Does anyone know how to increase the priority of the classic server
processes on Win 2000 server? FB version 1.5.2

The reason behind this all is that there was a pretty hefty stored
procedure in the db that has to be run once an hour. I was using
superserver and everything hung when the procedure ran (this started
after I upgraded to 1.5 from a really old yaffil classic server). I
changed the code so that most of the calculations were with the
application as opposed to the db, but this still wasn't too great. I
made the move to classic last night and it's made things better. _But_
the app is on the same machine as the server and it's started hogging
the cpu.
Any other ideas of what might work would be appreciated.
