Can you be more specific, please? The results vary a lot depending on the vecLib you use, which version of the OS etc. because Apple was improving vecLib support substantially. The same is true of Windows - depending on your BLAS the results will vary a lot. Comparing G5 vs MacBook is quite irrelevant because they are entire different architectures and Windows doesn't run on G5. If you have some specific examples, please let me know so we can test it. Note that R 2.4.0 on Mac OS X allows you to switch between various BLAS back-ends very easily, so you can choose the back-end that suits your application most.
