Oh, sure, I'm not saying I thought there would be no size difference; I was just bemused at the suggestion there was a performance difference. Unless "won't fit in ROM any more" is considered a performance problem ;-) -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours. We can't possibly take such a retrograde step." - 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/
