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.
