Bruce, Not to suggest that your results are anything less than the perfect truth of the reality of the matter, but I'm a bit surprised by this. Can I ask what kind of hard drive you had - was it anything especially fast? Also, I think memory speed is a very important and grossly underrated performance parameter. One could do a kernel compilation and compare the results between various memory speed settings as a test. In fact, I suspect that many online performance tests and benchmarks skew their results (say to favor Intel over AMD, or whatever CPU they want to show in a better light) by using a lower memory speed motherboard setting with the "designated loser" than the actual RAM is rated for. Most readers will focus on the CPU clock speed and will miss such a difference.
