Running the same test but with a highlight phrase in place ups the numbers somewhat:

char[] 35k
java.util.LinkedList$Entry 27k
Object[] 27k

etc. The vast majority of these are allocated within Lucene's search functions so I'm going to leave this as it is for now and re-examine it when we update to Lucene 1.3. It's only the first time the user views the table from a result list that they'll see these performance hits - thereafter we don't highlight search terms.
