Adding a new document does not immediately modify an index, so the time it takes to add a new document to an existing index is not proportional to the index size. It is constant. The execution time of optimize() is proportional to the index size, so you want to do that only if you really need it. The Lucene article on http://www.onjava.com/ from March 5th describes this in more detail.
