On a pii the slowdown is probably more than 1%, the slower the cpu, the more 100hz is appropriate. This is not going to be very noticeable on a desktop since a desktop is often idle, but only on servers it should help (for example kernel compiles will be more than 1% faster). - 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/
