This could well be IO bound - lots of seeks and reads. Perhaps try on a normal filesystem and see if you still see the serialization - someone recently saw some funny results with tmpfs and lucene, so it would be good to rule that out. If you want to try and rule out tomcat, throw the webapp in jetty. -Yonik http://www.lucidimagination.com
