I assume you put it on and endless loop since hackbench 10 runs for .5 second on my machine. Doubtful it's an SMP issue. update_if_moved should maintain cross cpu scheduling decisions. The same slowdown would happen on UP and is almost certainly due to the fact that hackbench 10 induces a load of _160_ on the machine. -- -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/
