I think we need a lot of more sample than just one computer. If we're enabling this on x86 processors, I'd like to see samples on following architectures:

AMD: K8 (was one of the most popular processor lines for AMD), K10 (still used in many laptops), Turion or Fusion, and Bulldozer.

Intel: Nehalem or Westmere (there still quite few NetBurst architectures CPUs), original Core, Core 2, and Sandy Bridge.

Quite frankly, the variation of cache size, bus speed, branch prediction mechanisms and accuracy etc... between these architectures is so large that I'm highly skeptical that this optimization is helpful on the average for x86.
