While I was working on Dementium II HD, I wanted to migrate the repository from SVN to Git. It was being hosted on a machine in the one studio and served the external developers over a 10mbit ADSL connection. The upstream rate is ~400kbit, so imagine trying to checkout a 26GB repository. I ran into the following error when I tried to import the SVN repo into a Git one:
$ git push -v origin svn-merge-trunk:svn-trunk
Pushing to https://git-repo/git

Delta compression using up to 4 threads.
Compressing objects: 100% (2788/2788), done.

After a bit of Googling, I found a solution for this:
$ git config http.postBuffer 524288000
$ git push -v origin master:master

Patting myself on the back and stopping mid-way to my back, I realized that both GitHub and BitBucket do not really support repos bigger than 1GB and I was sitting with 26GB :) All the art assets had been committed as part of the code repository and I did not know which were needed and which weren’t. The other devs / designers on the team were not familiar with Git and we decided to rather stick with SVN on a micro AWS instance. Interestingly enough, the CPU on the micro instance affected checkout speed - when changed to a small instance, the checkout speed doubled.
