There are several things that you should be aware of. First, did you clean
the log files after converting the repository? While cvs2svn does it's
thing, it commits to the repository leaving behind log files. You need to
use 'svnadmin list-unused-dblogs' to get a list of the unused log files that
you can safely delete. BDB 4.2.x takes care of this problem by automatically
removing log files itself. I imagine that you didn't do this, and that's why
your repository looks so large.
Second, stay away from BDB 4.1.x. We've seen database problems from people
that have been using that version. Apparently there are some issues with
their shared memory implementation that causing sporadic repository
corruption. I highly recommend using BDB 4.2.50. You'll get some speed
improvements, and automatic log removal which makes it a little easier to
maintain.
Finally, our latest version is always the best. You'll probably find little
change in cvs2svn, but there have been a number of user-visible changes since
0.33.0 in the command line tool. Be careful if you takes this step though,
you will need to 'dump' the repository and 'load' it after you upgrade. An
example of how to do this is in the FAQ at:
http://subversion.tigris.org/project_faq.html#dumpload
I hope that answers some of your questions!
