By "broke" people mean that the celerons do not have a cache architecture that can efficiently handle SMP. So rather than getting close to a 2x (1.75) performance increase for 2 CPU, you get more like 1.5 or so due to cache coherency effects. In the MP world, this is really bad performance. It will work, but it scales poorly. I don't recall if this is due to reduce coherency functionality, or is just an artifact of cache sizes. You really want to have 1M or so of cache for CPUs in this class. Warner To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
