The news here is no news. It is typical for early builds to not show significant change. News would be have if developers were already seeing huge changes in performance, size, security, etc.

Such testing also breaks the NDA I am sure. It is useless as the code most likely has debug support enabled which slows things down.

There is NO 32 bit/64 bit versions of MacOS X like there is for Windows. There is just MacOS X, which runs using 32-bit code when the CPU it's running on only supports 32-bits, and runs 64-bit code when the CPU it's running on supports 64-bits [and runs 32-bit code if the app isn't built with native 64-bit support].

I'm sure the first round is changing the code base, get it stable, and then ramp performance.

...to Entourage - Good Riddance.

What they are doing is comparing the OS on 32 and 64 bit machines, which, in turn, uses the correct binary (32 or 64 bit).

Thus, while it might not be 'written correctly', the testing is valid.

And, since one of the supposed features of Snow Leopard is the creation of Grand Central (why, exactly, does Apple feel the need to assign 'cute' names to underpinnings is beyond me, it isn't like users are going to give a crap about it), you aren't really going to see an increase in performance until (a) the API gets set up, and (b) programs take advantage of it.

"(why, exactly, does Apple feel the need to assign 'cute' names to underpinnings is beyond me,.........."

Because they can. You asked and answered your own question. Why? because they can and as you said their user's aren't going to see anything but the operating solution.
