Pre5, which I performed about the same as the others in the my low memory test and which I ignored in my even lower 12MB test looks quite good here. Based on it's good performance here, I decided to run the 12MB kernel compile test on it, as well. (See what happens when I try to cut corners...)

Based upon the tests that I have run, anyway. I agree with the person who expressed a distrust of benchmarks. But numbers are necessary for tuning. "Feels faster" is just not a very trustworthy thing. So I also agree with one of the responses: "Try out your favorite apps and time some portion of them and post any interesting numbers." (paraphrased) Benchmarks are not the problem. The problem is the lack of comprehensiveness, or the tunnel-vision if you prefer, that benchmarks can lead one into. Find a way to quantify the things that you do everyday and post the results. -Thanks -Steve -- This is a majordomo managed list.
