Does anyone have any clue as to why when I run the same version of BOINC on my Mac PRO (the baby, 2x 2.8GHz Xeon x 4 cores each) in Mac OS X, the benchmarks come in @: 3288 Whetstone (per CPU) + 12360 Dhrystone (per CPU).

When I boot *natively* into Vista, instead I get 2943 Whetstone (per CPU). Not much of a difference, but still a difference nonetheless.

On the other hand, for the Dhrystone in Vista I get @ 5881 (per CPU)!!! That's a massive difference in favour of OS X.

Now, admittedly I only have the 32 bit version of Vista (for gaming only, obviously), but OS X isn't fully 64 bit itself yet anyway.

Moreover, I am not sure how a bigger memory address space is going to help improve the benchmark in OS X so much when I only have 4GB of RAM installed anyway.

Any ideas what gives?

It's a known fact, that different OSes reports different benchmark results. Don't know excatly why.
But, the whole benchmarking system is totaly irrelevant for the credits in SETI, because SETI makes server side fixed credits by the floating point operations on the server side.

This most likely has to do with the differences in the compilers and optimization and function libraries used in the individual builds for the different OSes.
