Presumably, 127/128 runs have both the test file and the single header file in memory cache, so the distinction is moot.

Also, I find the conclusion that we should all just buy top end machines and ignore performance problems that don't manifest there fairly unconvincing. I think that kind of thinking is responsible for a good chunk of the reason the web is so bloated today. :-)
