Thanks for that explanation John.

Thanks Ben, I'm aware that --delta's does compress, however 11MB to
2.4MB is quite a high compression ratio, which was why I was concerned.

If you read the rest of my original post, I did indeed then try a plain
svnadmin dump which was still only 5.8 MB - about half the size of my
respository.
