Let's consider the difference between the 2 systems:

170-2290:
   Processor: Northstar 200 Mhz.
   L2 Cache: N/A
   RAM: 320 MB

170-2385
   Processor: Northstar 252 Mhz
   L2 Cache: 4MB
   RAM: 1 GB

If not cache, then what would account for a performance improvement of 11
times?  Both systems were doing very little other work at the time.  The
work is entirely CPU bound.
