Me too -- but entirely possible. Disk IO is specially painful on OSX.
Stat calls are horrid. Using Arch (which abused stat calls to no end)
many ops would take 50x-100x longer on OSX than on Linux. A large
unpacked repo with git is a real pain -- and packing it can take
hours.

Once you are packed it's sweet, but large repos are a pain to deal
with. You won't impress anyone with performance over a linux kernel
repo -- starting up gitk can take a long time. Stat-heavy stuff like
git-diff is noticeably slower under OSX.

Have you got a linux partition you can boot into to get comparative timings?

[This is part of the reason I am migrating my OSX machine to Linux
fulltime, now that it seems that mergedfb+randr will let me switch to
dual monitors "hot".]

cheers,
