Okay well, I've got a couple more machines to join in on this which I'll get running tomorrow, to make my contribution up to 8 cpu's.. Some stats from this that amazed me : (seriously) My desktop P166 (32Mb Ram) not much load at the moment is doing 200kkeys/sec. With 2 processes running on a dual processor P133, each process is doing 180kkeys/sec. The thing about this is that a p133 doing something like this that I would have thought of as processor intensive should only get 133/166 the speed of a P166 (okay so that's obvious). But 180,000 / 133 * 166 is 224,000. i.e. FreeBSD-SMP on very similar hardware here seems to be actually outperforming my desktop system. Maybe it's late in the day and I'm missing something obvious, but it's a nice sign to go home on. =) Steve -- Steve Roome - Vision Interactive Ltd.
