Benchmarks When running tests, installing operating systems, and compiling software for my Ultra 5, I came to the stunning realization that hey, this system is 64-bit, and all of the operating systems I installed on this Ultra 5 (can) run in 64-bit mode.

I don't think that's the sort of "optimization" the original poster was talking about, especially since the technique is entirely irrelevent to the benchmarks presented in the article.

Plus, what you are talking about is not so much optimization as it is getting rid of hacks that are no longer necessary because of a more permissive CPU architecture. Optimization takes general code and tunes it for a specific situation. What you are describing is actually the reverse --- taking code tuned for a specific situation (low-memory) and generalizing it.
