cvs vs svn repository size

Sorry if this has come up before - I could not find a suitable answer
online.

I'm currently investigating converting some cvs repositories to
subversion and have discovered that the svn repositories are taking up a
lot more space than the cvs originals.

I have run a couple of tests -
. A script to do 500 commits of random line of text to a file (fsfs):
    CVS Repository: 764k
    SVN Repository: 4.3M

. A conversion of one cvs "repository" using cvs2svn:
  (trunk only, fsfs, ~15,000 revisions)
    CVS Repository: 109M
    SVN Repository: 614M

Why am I seeing such bloated repositories? Svn is using 5-6x the disk
space when I expected to see just the opposite.

Is this a case where the changesets are small in comparison to entries
list?

Is there anything we can do short of restructuring our repositories?

Thanks,
Eric Miller
