A benchmark that probably relies as much on disk access speeds as CPU?

Nope, 7zip is using LZMA algorithm for compression, which is around a few MB/s on the fastest CPU. It's heavily CPU bound.

edit: Just tried compressing a large file, ultra setting on my desktop i5 CPU, it's running at 3 MB/s on 1 core.

Apple ships a framework for doing lzma and other compression algorithms. I doubt they will be taken by surprise

One large file could be CPU bound, many small files (which is partly why you zip/jar things up) is disk bound.

Not true. the bottleneck is going to be compression not disk access.

If true, that's just a nitpick that doesn't affect the overall point of the GGGP, though.
