Back in the bad old days of $30+ DRAMS, we bought a 16Mhz Mylex motherboard.
This mother has a 64K cache and 120ns main memory.  Running the Dhrystones
(under 386/ix 1.0.4) on it gave 4950 'stones with the cache turned on (~0ws),
and 3652 'stones with the cache turned off (1ws).

Your results may vary...
