repository sizes in different versions?

[Les Mikesell <le...@gmail.com>]

I have an old repository that I think was started with a 1.4.x version 
of subversion, then updated in several stages to 1.6.5 without doing any 
changes to the repo format.  Du says this repository is taking about 38 
gigs of disk space.  I've recently duplicated this repository using 
snvsync from a system running 1.6.6, copying approximately 120,000 
revisions.  Du says this repository uses 1.9 gigs of disk space.

Is that reasonable - or at least possible?  Does it mean I should do 
something to compact the original copy?

That's a pretty big difference but I suppose it's possible it's ok. Could be a consequence of rep-sharing. If "svnadmin verify" says both repositories are ok, they should be ok. You could check that they have the same number of revisions, and check out a few random revisions of each repository and then diff the results to convince yourself they're the same.
