I found some tweaks to the code that give me a 65% performance increase. I'm using JDK 1.5. Let's see if I can attach a patch here... --------------------------------------------------------------------- To unsubscribe, e-mail: commons-dev-unsubscribe@jakarta.apache.org For additional commands, e-mail: commons-dev-help@jakarta.apache.org
