Hacked up test case below ...
This one seems to do benchmarking with 8MB buffers if I read it right 
(didn't try).

The normal size for the performance-critical git objects are in the couple 
of *hundred* bytes. Not kilobytes, and not megabytes.

The most performance-critical objects for uncompression are commits and 
trees. At least for the kernel, the average size of a tree object is 678
bytes. And that's ignoring the fact that most of them are then deltified, 
so about 80% of them are likely just a ~60-byte delta.
