It'll still be half speed.
The md5sum would be of the final, compressed form, not the uncompressed
data.tar. When checking the md5sum, the data.tar.gz would have to be read
from .deb, and then when extracting it, the data.tar.gz would have to be read
a 2nd time.
As Wichert as said, doing this would be a hack around the real problem. That
dpkg doesn't clean up when an error occurs during extraction(at least not in
this case).
