cvs2svn: Conversion taking a very long time

From: Mike Crowe <mac_at_fysh.org>

I have been trying to convert a sizeable CVS repository to subversion using
the version of cvs2svn on the 1.0.x branch in r8550. I realise that this
isn't really the latest version but the reason for that will become clearer
later.

I've looked through the issue tracker and couldn't see anything
particularly appropriate.

The CVS repository is five years old, just under 2GB in size, has 622
tags/branches and around 50000 files. The repository is a mixture of files
that have had only one or a handful of revisions and files that have had
several hundred revisions.

I've left cvs2svn running for 25 days on an otherwise idle 1GHz P3 with
python taking around 98% CPU. It doesn't appear to have used much swap. In
that time it has "added or changed" nearly 130000 revisions and appears to
have processed around 36000 of the files in the repository.

So,

1. Is this the expected behaviour on a large repository with lots of tags and
branches?

2. Is there anything I can do to the repository to make it faster? Some of
the tags could probably be removed for example.

Obviously having to wait over a month for the repository to be converted
would severely impede our ability to migrate to Subversion :(
