Don't worry about it. Subversion never scans these directories.
The only cost is going to be in using non-svn tools, which is not
necessary. svnadmin hotcopy/dump should satisfy backup needs.
Or you could just do what i'm doing and copy the revprops, revs,
and current files in post-commit. But there's never a need to
scan these directories.

open's speed is not affected by the number of entries in a
directory.
