Last night I decided to see what storage size differences I might see
between an svn repo and a git one.  So I imported a highly used
subversion repository into git and was shocked to see how huge the git
version was.  I used a repo that has a lot of branches and tagged
releases just to make sure importing into git would in fact keep all
of the history.  It did keep the history, but the total disk usage was
very different:

$subversionbox # du -hs ./my_sample_website/
67M	./my_sample_website

$localhost # du -hs ./git-samplesite/
3.6GB ./git-samplesite/

Here are the steps I took (locally):

mkdir git-samplesite-tmp
cd git-samplesite-tmp
git-svn init http://subversion.myco.com/my_sample_website --no-metadata
git config svn.authorsfile ~/Desktop/users.txt   # mapped svn users to git users
git-svn fetch
git clone git-samplesite-tmp git-samplesite

I did this based on reading the documents in the git wiki, so I
assumed they were "best practice."  Did I do something wrong?  If this
is a normal amount of storage need increase, we'd likely not move to
git based on the need for new hardware alone.

Any help would be appreciated.
