Repo is huge after svnadmin dump/load

I needed to make a "sanitized" version of my repository by getting rid
of source files and all of the history. I did the following:
1) Used svnadmin hotcopy to copy the repo
2) Did a checkout from the copy
3) Deleted everything that's sensitive in the WC
4) Did svn commit back into the copy. The commit created revision 578.
5) Did svnadmin dump /path/to/copy --revision 578 >dumpFile
6) Did cat dumpFile | svnadmin load /path/to/sanitized/repo

My original repository size is 560.6 MB.
My copy repository size is 560.7 MB.
My sanitized repository (created by svnadmin load) size is 3.19 GB.

I am wondering why the sanitized repository is so large.

I am using svn 1.4.3 under Mac OS X 10.4.10. The back end is FSFS.

I can run svnadmin verify successfully on the sanitized repository. It
displays:
* Verified revision 0.
* Verified revision 1.

I didn't find anything pertinent searching in Google. Does anyone have
any idea why this would happen, and/or how I can get the sanitized
repository back down to a reasonable size?

Thanks,
Rush
