More info on the SB2500 :-

Not exactly a benchmark, and certainly not scientific, but this
morning I installed Rational/IBM "PurifyPlus" and ran my appplication
through purify. For those not familiar, this tool instruments object
code with memory watching instrumentation for errors like
"uninitialised memory read" "array bounds read" and so on and so
forth. I consider the tool essential for C++ development.

Anyway, I'm happy to say that the SB2500 is "wicked fast" at this
particular job. My perception is that the improvement is better than
the raw clock speed increase over my previous dev machien (SB1000
750mhz). Could be due to improved (lower) main memory latency and much
fast 2nd-level cache. Whatever the reason, I'll take it!
