Let me drop one of my pet complaints here, that the install programs of many (most? all?) commercial releases don't give you a stripe size menu to let the user make a decision based on intended use. Instead the program uses the "one size fits all" approach and picks a size. As you say here it's not unreasonable in terms of being typical, but for most people it such for performance. As you noted elsewhere big stripes are almost always better, and a default of 256k or so would work better for most people.
Sorry, related flamage, but your comments welcome, since this does affect the perception of performance of the o/s. -- bill davidsen <davidsen@tmr.com> CTO, TMR Associates, Inc Doing interesting things with little computers since 1979. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
