Star Solaris and Windows Performance Compared
Linked by Eugenia Loli-Queru on Tue 24th Oct 2006 04:33 UTC, submitted by mcsimpson
Benchmarks A benchmarking comparison of Solaris 10 and Windows XP (64bit) running on a Sun Ultra 20 M2 Dual Core Opteron 1210 workstation. "Overall, I'm pleased with the performance of the Sun Ultra 20 M2. While this model (with an Opteron 1210) isn't quite as fast as a low-end Mac Pro, it's less than half the price of a low-end Mac Pro. Models equipped with faster Opterons (like the Opteron 1218) will certainly be more competitive when it comes to performance."

Given the processor is the same, there'd be no difference whatsoever in the generated code between the two platforms.

So you could copy a g++ executable from Solaris to Windows and have it work! The API's for the 2 OS's are totally different. Simple things like register assignment (which is different) can dramatically change the compiler optimization choices, therefore the code produced is different.

The API has got nothing to do with code generated for algorithms. Of course, say, opening a window on solaris is done differently than opening a window on windows, but the point is exactly to measure the relative performances of doing similar tasks on the two OS's.
