You can't blame MacOS X mmap(2) for git's slow execution of "git log".
Here are is execution times of "git log tr.c > output"
- with git-1.5.0-rc4 built with -DNO_MMAP
real 0m26.032s
user 0m13.580s
sys 0m11.730s
- with git-1.5.0-rc4 built with the default settings:
real 0m25.469s
user 0m13.530s
sys 0m11.490s
You can see that using mmap() provides a speedup of about 2% on MacOS X,
which is similar to the 4% than Shawn measured on Linux.
