Subject: "Cache Profiler" ? (was: No cache control on ppc??)

Hi,

I recently installed a NewerTech Maxpowr G3 L2-Cache - which is a G3
on a board that fits into one of the L2's ram banks on my Starmax
3000/160. I was ecstatic that the bogomips increased by 187%
(199.47). Recently, though, I heard of someone installing a JoeBoard
into his StarMax 5000 and his bogomips being around 800. He mentioned
something about a "Cache Profiler". It seems that BootX is somehow
able to tell the kernel that there is a G3 in the cache and speed is
increased greatly.

The CPU on the StarMax 3000/160 motherboard itself (what originally
came with it) is a PPC 603e. /proc/cpuinfo shows a 750 - which is good
but the bogomips are nowhere near what this person reported.  I do not
use BootX for I prefer booting straight into Linux with Quik.  Does
anyone know anymore about this and if it's possible to increase
performance more by somehow making the G3 quicker?

Thank you,
Elizabeth
