That is not the expected behaviour, 1.9 would normally be smaller. Can you identify where the difference lies? For example: are the HEAD revisions the same? Are the db/revprops/ directories about the same size? Are the db/revs/ directories about the same size? Are the db/rep-cache.db files about the same size? You can run svnlook tree path/to/repo to get a listing of all the paths visible in HEAD, you should get the same list for 1.8 and 1.9. 1.9 provides svnfsfs stats path/to/repo which you can run on both the 1.8 and 1.9 repositories. -- Philip Martin WANdisco
