Which system (dual P5 vs. 1 P6) would be faster at > compiling all of FreeBSD from scratch? right now the single P6 would be faster than 2 P5s. How much longer that will be true I'm not sure, things are progressing nicely in the SMP kernel. 2 P5-200 might suffer from serious bus congestion. If you can afford it go for a dual P6 with one CPU for now, then add the second CPU when finances permit. There is not that much difference between a P5-200 and a P6 these days (p5-200s are overpriced, but then so are P6). I suspect (hope?) a decent price drop in P6 by February. 64 meg should do nicely unless you are doing something intensive. I have 64 meg and rarely hit swap. -- Steve Passe | powered by smp@csn.net | FreeBSD
