What version of git are dealing with on the client side?
I only have a MacBook Pro (2.4 GHz Intel Core 2 Duo) and I'm getting
fetch times of ~472 ms over git:// to your -tip.git tree and ~128
ms for strictly local fetch. If your SSH overhead is ~300 ms this
is only a ~700 ms real time for `git fetch origin`, not 5100 ms.
Is your git-fetch a shell script? Or a compiled binary? The port
into C made it go _much_ faster, even though it is still a naive
O(N^2) matching algorithm. Yea, we still should fix that, but
I think an upgrade to 1.5.4 or later would make the client side
improve consideribly.
