git-fetching from a big repository is slow

Hello,

I've got a big repository. I've got two computers. One has the repository up-to-date (164M after repack); one is behind (30M ish).

I used git-fetch to try and update; and the sync took HOURS. I zipped the .git directory and transferred that and it took about 15 minutes to transfer.

Am I doing something wrong? The git-fetch was done with a git+ssh:// URL. The zip transfer with scp (so ssh shouldn't be a factor).
