The jstack utility is good for this. > I'm not sure how to convince the Tomcat/Java container to spread its > threads among the cores. Convince your application; it's not Tomcat or the JVM. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
