Please have a look to the developers list at: http://mail-archives.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgId=1797569 where i made some measurements about the disk usage within lucene. At that time i proposed a patch which was reducing disk total used disk size from 3 times to a little more than 2 times of the final index size. Together with Christoph we implemented some improvements to the optimization patch and finally commit the changes.
