I've seen modern hardware run buildworld for days, but explode on scientific FP work in a few minutes. It used to be the case that buildworld would stress a CPU, but with all the specialty circuitry put into CPUs these days, buildworld probably ends up using the MMX and SSE extension silicon as a heatsink. A real stress-test would be something which engages bus-interface, integer, floating point and preferably any "extensions" as well. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
