Apart from the duplicate data for each file, svn writes quite a lot of files
that contain structural information, such as checksums, revision numbers for
each file, status information etc. These are all small individual files, if
you do some more extensive test you'll note that the number of files is a
large factor in checkout speed, instead of the total size.
