We need that processor to run applications, when the processor is
spending it's time compressing data it is most definitely NOT running
those applications!
The speed of the hard disk does not effect processor utilization, you
simply setup the SCSI DMA transfer and go back to running other
processes.
So we are going from maybe 5% processor overhead to 30% procesor
overhead per page (total guesses on my part).
That is NOT acceptable! NeXT should *FIX* the stupid paging problem,
not add a cold compress (:-)) to an open sore!
