You might consider non-ageing priorities on IRIX (see npri(1)). At
University we encountered this to be very useful as it allows to
idle CPU's but keeps interactive processes running. Be aware though
I/O by the OS is a non-prioritized demand and always comes first.
implies that if you have lots of npri'ed jobs and your machine
swapping the performance will again drop considerably.
