We have been using Subversion 1.4.x for quite some time and just earlier
this year, we upgraded to 1.5.x. Our repository is still the same as we
did no dump/load between upgrades. I was curious to see what kind of
space savings we might have if we did. Our original repository is fsfs
and was created under 1.4.x as far as I remember. The format file says
3 so I might have made it with 1.3.x. The format for the new repo is 5.
Here are the numbers for two tests I did, one with fsfs and one with
bdb.
737M svn-original
690M svn-fsfs
903M svn-bdb
2.3G total
Are these numbers typical? And why is BDB so significantly larger? Is
there any real benefit to it nowadays? Our server set-up is all access
must be through the apache user via mod_dav_svn.
