It's not easy to measure gc time, especially if it is based on generational gc algorithm which does NOT do gc for all objects. In addition, a single gc does not remove all obsolate objects. They are often removed at the second or third time gc. When you test, monitor IO activities as well, potentially stemming from virtual memory paging activities. It could be the one that makes gc much longer. Generally it's good to minimize object creation and use not too UNNECESSARILY large JVM heap. What many people practice is to recyle objects and threads. -- View this message in context: http://www.nabble.com/Tomcat-with-8-GB-memory-tf4149367.html#a11839991 Sent from the Tomcat - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
