make -j5 sucks you'll get precisely 1/6th cpu for galeon with this scheduler which is perfectly fair and I make no apology for it, nor do I plan to optimise for it. With make (without jobs) you'll still only get 50% cpu so it should be precisely half speed unless you nice it. Does it feel precisely half speed? It's supposed to. This is one of the drawbacks of a perfectly fair approach; its... fair and will need more liberal use of nice. -- -ck - 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/
