[rescue] More on Silicon Samsara

So far with this Ross 150, it feels just like my other SS20 with 2 SM61s. My
plan is to run BSD on it, so the extra speed will be nice since SMP is not
to be found in the BSD world. I think the extra cache is really only good
for server type tasks, for a desktop the lower amount of cache is offset by
the lower latency of the cache(from my understanding, the HyperSparcs have
less wait states).

I've really been in the market for SM81s but a killer deal presented itself
on this 150(less than $100), so I snagged it, now if I could find another to
go with it, for some SMP action....

I've thought about switching from superSPARC to hyperSPARC on my main
machine, but every time I look at them, I worry about the shrinking of the
L2 cache as the clock speed goes up. While you can get hyperSPARC CPUs
with 1MB cache, lots of them (all of the fastest ones, most of the slower
ones) have 256 or 512K of cache.

Presently, I run three 50MHz CPU's (thanks, Chad & Mike S!), each with a
nice, fat 1MB of L2 cache. Most of the hyperSPARC machines that I
administer at work have dual 125-150MHz CPUs, and are not appreciably
faster than machines running slower-clockspeed superSPARC modules with
bigger caches. So at thing point, I'm thinking "forget hyperSPARC"! ;)

Anyone else had similar experiences?
