rookie user, repo vs src vs co sizes

the directory sizes of the original source, an svn co of a new svn repo
and the svn repo itself are leaving uncertain. see the sizes below

original..........
kt@alvin /tmp/gamaco1[153]>ls
bin/ design/
kt@alvin /tmp/gamaco1[154]>du -s design
45916 design

svn co...........
kt@alvin /tmp/svnco1/svnrepo1[150]>ls
design/
kt@alvin /tmp/svnco1/svnrepo1[151]>du -s design
118340 design

the svn repo itself..........
kt@alvin /tmp[156]>du -s svnrepo1
9944 svnrepo1

i have read where the svn co is about 2x the size of the original. ok i
guess, but my bigger question is why is the repo itself sooo much
smaller than the original??? i can gzip the original and get closer to
the repo size but not close enough to make me feel good about.

what magic is going on? how can the repo itself be so small without
using links to the original? is this expected?
