BogoMIPS actually stands for "Bogus, Misleading Indication of Processor Speed"... In an old Linux Journal article I have (will dig it up upon request), it describes how BogoMIPS is calculated -- it's VERY processor-dependant, and only really (sort of) useful for comparing motherboards with the same processor on them..... Switch from an Intel 486/66 to an AMD 486/100, and the numbers do NOT match up to what you'd think.... And if you change to a Pentium, forget it. The biggest thing it's good for is as an ego-booster.... Of course, my dual-PII/450 box has a bigger BogoMIPS rating than any machine at work.. :) --mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
