I just did a small test on a repository on my desktop, almost entirely
textfiles stored in it. Originally created w/ SVN 1.2.3, FSFS.
Original was about 49 MB, 397 revisions. The dumpfile came out to 200
MB, and when I loaded it with SVN 1.4 into a new repository, it came
out to 32 MB.

A second repository on my system with more binaries (PDF files, as
well as source code), has 387 revisions and takes 97MB on disk.
Dumpfile was 123MB, and when I loaded it into a new repository, it
came out to 90MB.

YMMV, of course. I'm sure that changes in repository size will have a
great deal to do with what you're keeping in the repository. Both of
mine decreased in size, but the smaller repository had a much larger
(percentage-wise) reduction.
