binary files and repository files

hi !

i have installed subversion because i have read that it is 'efficiently
handling binary files'
what i wanted to use it for:
i have a directory structure of compiled software, this is replicated to
all servers where the software is running, size of the tree is cca 60mb

sources are in cvs, i have build/deployment mechanism to handle most of
the tasks automatically
i also have a possibility to rebuild the tree with the software version
from the past - but it takes quite some time to compile everything
so i was thinking of storing important versions in a subversion (these
are binary files mostly)

however, to me it seems like repository size is always increased by
size_of_changed_files * 2

i have imported part of the tree, 33mb; repository size was 70mb
then i have replaced one binary file (500kb) with a new version and
almost the same size -> repository size increased by 1,2mb
then i have replaced another binary file (700kb) with a new version and
almost the same size -> repository size increased by 1,5mb

these were jar files, and i can understand that they are zipped and
therefore even a small change in a source code can lead to completely
different content
if the size of the repository would increase by the size of changed
binaries plus some kilobytes of meta data - i would be happy

can anyone explain me why is the repository size increasing so much with
every commit ? can i do something to minimize this ?

thanks !
