I suppose the original packages tar file ontains the documentation files
uncompressed whereas the .deb package installs these files as

So they are compressed in one gzip run in the .tar.gz, whereas in the
.deb case all files are compressed individually and then compressed
again by dpkg --build. This makes the overall compression less
