Ran BOLT on the adpublisher binary – with name similarity function matching, total execution time of rewrite passes was 2235.2883 seconds (1989.1823 wall clock) with an edit distance threshold of 20 and 2194.1708 seconds (1986.2007 wall clock) with an edit distance threshold of 10. Without name similarity matching, total execution time of rewrite passes was 520.4121 seconds (296.4178 wall clock).
