Mac OS X Some detailed benchmarks of Snow Leopard. "The performance improvements we encountered in Mac OS X 10.6 through our benchmarks we were quite astonishing. Thanks to the introduction of the Grand Central Dispatch, 64-bit migration, OpenCL support, and other refinements made "under the hood" of Snow Leopard, this is one hell of a fast operating system. We were quite appalled with multiple tests exhibiting nearly 50% performance boosts over Mac OS X 10.5.8. While that was an extreme improvement, many other tests ran 10~16% faster. In a few tests, the performance was the same or the delta was statistically insignificant, but in a couple tests, there were regressions."

That's because, SL now reports drive sizes in powers of ten. ;)

Correct. 300 GB free in Leopard will actually show as 322 GB Free in Snow Leopard.

Leopard:
300GB x 1024 x 1024 x 1024 = 322122547200 bytes

Snow Leopard:
322122547200B / 1000 / 1000 / 1000 = 322GB

This is the main reason for the disk space free-ups in Snow.

The gain in space doesn't come from the new base 10, as the used space will be in sync with free space.

I.e. in leopard 320gb hdd shown as 293GB after format with 20 GB used = 273

in SL 320GB hdd shown as 320GB after format with 20GB used = 300GB

still loosing 20GB either way.

You really gain the space from smaller binaries, less printer drivers etc..

BTW, is this change limited to how disk capacity/free space is shown. Or all of Finder now shows usage in powers of ten?

My copy of SL is on its way, but I'm curious about this.

I also gained around 14GB of hard disk space back!!
