If you could increase the cache memory up to 1 Mb the improvement would be
amazing.
I have done many benchmark tests fooling around with L1 memory and both OS2
and Windoze starve for it, at least up to a meg.
The newer systems may bes equipped to handle this problem but the older ones
with 256K maybe less are not.
