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".]
