I have created a small testcase script:


for i in `jot 15000`
cat > Testfile_${i}.txt << __END__
This is a small test file.

This is a small test file.

svn add Testfile_${i}.txt
svn commit -m "Iteration $i"

After the 15000th commit, the size of the repository on disk is 5.5G
with the working directory size being 120M. Besides, after several
thousand commits to this directory SVN slows down considerably. This
must be some design flaw (or peculiarity if you like) of SVN.
