Chuck is right:  the "twice as much" is du
reporting in the default 512 byte blocks.
You probably have the BLOCKSIZE=K set
in either ~/.profile or /etc/profile.

If you recently upgraded sudo, you should
take note that env_reset is now the default.
You can return to the old behaviour by adding
a line like:
Defaults !env_reset
to your sudoers file.  It might be more secure
to not do this with a Defaults line, though.

man 5 sudoers for more information.
