[rescue] When it comes to cache - I want as much as possible!

[Ken Hansen]

Geaorge,

Granted this is a totally different arena (x86, not
SPARC arch.), but I had occasion to try and re-purpose
an old P90 box as a thin client running Linux on
Friday. As I was trying to get through some hairy
video problems, I disabled the 256K cache.

It made a profound difference, *easily* 15-20%
performance hit, just doing the install...

While I agree that 256K on a SPARC or UltraSPARC is
*almost* nothing, it makes a *huge* difference over
*nothing*...
