for power saving, the ondemand behavior is better in general. However if you have a cpu that switches frequency very slowly, you may be better to not go as high quickly because going back down is then burning more power than needed potentially... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
