... but only if you spend most of your time running CPU benchmarks :-) Your results show a 50-100% speed increase for operations requiring a lot of kernel activity. Remember also that interrupts etc. cause a background rate of cmpxchg instructions that is quite high. On slower CPUs (I was using a 400MHz PII), the interrupts can soak up virtually all of the available processing capacity without the patch. I suspect this effect is responsible for the most dramatic speedups. Ian To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
