Ah yeah, 32 bit under a 64 bit environment will actually be a tad slower. But I don't think it is noticeable. Then again you will have the full 32 bit address space available under the 64 bit environment.
64 bit all the way baby! :smile:
No it really doesn't does it? If you recompile something for 64 bit an run it on a 64 bit windows you will actually see a 5-15% increase in performance AFAIK.
But it is not that easy to just recompile such a software. They will need to clean up data type incompatibility and such.
But the OOM issues are actually a big deal and it is worth porting the platform to 64 bit. It will be vital for the platform to survive.
