Intel Providence (PR440FX) mobo, one 64 MB DIMM
Two Pentium Pro 180/256 overclocked (solid as rocks) to 200 MHz
FreeBSD 3.0-031198-SNAP
Running two RC5 clients, each in its own xterm, each process averages
around 526 kKeys/sec sustained, for a combined key rate of around 1056
kKeys/sec.  If I don't run X Windows (or anything else for that matter) and
run them in two virtual terminals, I have seen both processes average 537
kKeys/sec.  This is not bad at all (my single-cpu Cyrix P166+ gets 309
kKeys/sec), BUT...

I believe fully that a dual PII-300 system (as the original poster was
questioning about) would handily beat this key rate.  Probably by around
50% ;-).  The benchmarks show that a single-cpu PII-400 system will just
barely (by up to 50 kKeys/sec) beat the combined output of my dual PPro 200
system.  You have to remember that the RC5 client uses a code core and data
chunk so small that they easily fit in the cpu's internal cache, so RC5
client speeds are NOT a good general benchmark.
