It is of course CPU speed dependent, it's the CPU that is running the 
test.  More over a G3 or G4 upgrade won't help much.  While the 
processor runs at it's higher speed the Backside Cache isn't active 
until the appropriate extension loads at startup which is after the 
memory test.  Also of course you are limited to the throughput of the 
computer bus with regards to how fast you can access the memory to 
test anyways.

The part about the cache applies to non-G3/4 native systems, machines 
that shipped with a G3 or G4 would, I think, have the cache enabled 
before the memory test.
