Ugh. I hope you are talking about checked-out size.
[torvalds@i7 linux]$ du -sh .git
850M .git
because otherwise it sounds like that repo hasn't been repacked in forever.
To really pack things (which can slow things down for old history as
people said, but on the whole it tends to be a big win due to less
IO), do
git repack -adf --window=200 --depth=200
and go away for a while. Oh, and make sure your machine has enough
memory and CPU to make that "for a while" not be *too* long.
You should have a few hundred files (just a few tens of files directly
after the repack) and that roughly 850MB of space for the repository
information itself.
But yeah, fully checked out and built with all the modules etc, you
would have much more.
That said, if you have something fairly that is consistently really
slow (like the "git commit" you mentioned), *before* doing the repack,
do
strace -o ../trace-file -Ttt git commit
and we can get a much better guess about why it's so slow. Send it to
me in private email if you don't want to make it public, and I can
take a look.

.. and I *really* hope that was not seconds, but ms. Otherwise your
nfsv3 setup is going to be really really painful.
