I also added the -XX:+UseCompressedOops JVM option (as suggested in the Confluence article I mentioned earlier). BTW, for those who want to know: this option is available since update 14 of JDK 6 (see also http://java.sun.com/javase/6/webnotes/6u14.html), you don't need the "Performance branch" as mentioned in the article. This option is said to give a performance gain of 25% as well as a reduction of used heap space (see also http://blog.juma.me.uk/2008/10/14/32-bit-or-64-bit-jvm-how-about-a-hybrid/).
Furthermore, I discovered the -XX:+UseTLAB option is a default option in JDK 6: http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp I thought, I'd just let you all know! -- View this message in context: http://old.nabble.com/Tomcat-100--CPU-usage-after-moving-from-Java-5-to-6-tp27305110p27322864.html Sent from the Tomcat - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
