Git repository 8GB 5000 git branches, performance issues when converting?

[Uwe Brauer]

I today cloned a git repository of around 8 GB with 5000 git branches.[1]
Since I don't like bookmarks I usually clone a git repository with hg-git and convert the git branches to named branches.

In this case I would then deal with a 16 GB repository with 5000 named branches.

I presume this would cause performance issues?

Can this conversion process be interrupted and then continued or
will it start all over again?
