Yes.

It is highly likely that almost all of your repo space is being taken
up by identical new files that should have been copies, but cvs2svn
borked it :)

It is likely that git properly notices they are all the same data, and
just shares them when you do a git to svn import.

If you stare at the dumpfile that cvs2svn generates, and look at the
commits that create your branches, you can see if it is properly making
them copies or not.

This is being attacked two fold, by working on fixing cvs2svn, and by
working on issue 2286.
