Re: svn back-end question

Jean-Pierre,

I've only been using SVN for a few months and I haven't stressed it yet. I
will eventually have 200-300 users hitting one server. The problems I am
encountering have more to do with slow network performance in my environment
than anything subversion related.

A few things to think about:
1. You can change the type of back-end you use later by dumping and
restoring.
2. As a reformed CVS user myself, I found the fsfs repository more useful
while learning to use svn since I could directly examine the files in the
repository. It just makes is easier to understand what is going on.
3. The one concern I have about fsfs is with the number of files in a
repository. I have conerns about what happens when there are many thousands
of revisions in a repository. Unix filesystems traditionally do not handle
that case very well (I'd like to see svn modified to use a hierarchical fsfs
repository - no more than 1000 files per directory).
4. The way I read the documentation it implies that the berkeley db back-end
will be deprecated at some future time. Some of the developers (Ben) have
recently said that this is not the case, but, nevertheless, that's how I read
it.

Best of luck,

Daniel
