I own a PW2 Series 850 (a.k.a Mitsubishi MP-386, a 386-based PC-AT
compatible).  Straight out of the box, it comes with a 32KB "direct-mapped
cache".  With the addition of 9 SRAMS and switching some jumpers, the cache
becomes a 64KB "two-way set associative cache".

What is the difference between the two caches and what kind of performance 
increases might I expect from the 64KB cache?
