[converting scarab] high repository size after cvs2svn

The scarab project [1] has decided to give SVN a go.

I played with cvs2svn yesterday. My current problem is the repository
size which is about 8 times higher than the corresponding CVS one.

I am using subversion 0.33 which is the current version in Debian
> grep LastChangedRevision `which cvs2svn`
# $LastChangedRevision: 7729 $

A newer version, probably 0.37, should come really soon in the
repository according to the maintainer [2]. I will upgrade ASAIC.

To convert, I did the following:

# cvs/scarab contains the scarab cvs module

> mkdir svn
> svnadmin ./svn
> cvs2svn -v -s ./svn -v cvs/scarab

I first made a dry-run which took 45 seconds to complete.
I then made the full run, which took a little bit over 3 hours to
complete. (config PIV 2.6 GHz, 512 Mo). > 90% CPU in execution.

I didn't test the repository yet, but my results are disturbing:

jerome@dolcevita> du -sk cvs svn
235784 cvs
1991752 svn

In other words, subversion uses much more space than cvs in the
repository (> 8 times).

I couldn't find any reference to such issue in the issue system.

I am completely new to subversion so I perhaps made a mistake and missed
an option/config.

Perhaps 0.37 will help, as 0.33 still uses BDB 4.1 in Debian. 0.37 will
use 4.2; should that help?

Would be happy if someone could shred some light on this issue?
