There's no reason the size of the working copy needs to directly
relate to the size of the repository.
For one thing, the working copy contains two copies of every file: a
pristine copy inside the text-base directory in the .svn directory,
and then the normal copy that you might modify. This enables
Subversion to determine what you changed without having to contact
the server.
For another thing, you might have copied things in the repository.
For example, if you have a 1GB directory that you committed to the
repository, and then you used "svn cp" to copy this directory to
another directory, the new copy occupies virtually no space in the
repository. It just stores the fact that it was copied from these
other files in that other revision. But if you check out, you'll get
all 2GB (plus another 2GB of pristine files tucked away in .svn).
So, it's not hard for your working copy to be larger than your
repository. The opposite is also easy -- commit lots of files, then
delete them. They're still stored in the repository, but you won't
get them if you just check out the HEAD.
