As far as I know, the operations that make MMX better than pentiums are
the abilities it has to manipulate packed data. Until there is a machine
description and an optimizer for these cpus written into gnu cc, there
will be very little significant increase in performance....
Not that the orgs won't try to support them very soon, remembering
that un*x supporters are trying to keep unix as the IP-working standard,
the web standard, and all.
Pentium MMXs don't often cause much performance increase in everyday
operations, but their increase in blitting, etc. should be incredible.
cheers,
John
