Hi, We are trying to upgrade Tomcat from an older version 3.x to 5.x and noticing that Tomcat 5.x requires quite more memory than 3.x. We are running it in constrained env. with limited memory and other resources. In order to fully explore all possibilities, we also ran Embedded Tomcat for our web apps and it seems to be saving some memory but not significantly less than regular tomcat. (About 3MB saving in embedded) Regular tomcat 5.x with our webapps(total 5) takes about ~66m (RSS portion) Embedded tomcat with above apps takes about ~63m (RSS portion) I am curious to know are there more tweaks that can be tried on Embedded Tomcat to reduce memory usage further ? We tried Embedded Tomcat that creates shared class loader and set it as parent classloader on Tomcat engine and adding all of our webapps context in engine, which seems to be saving memory upto 3 MB. Is Embedded Tomcat going to help further in reducing memory usage in general (more than 3mb) ?
Are there more ways to reduce memory in regular Tomcat 5.x ? (server.xml is pretty much trimmed down to bare minimum, no JMX listens, min threads , no extra connectors etc) What portion of Tomcat code internals we can not build Or trim in regular Tomcat to save more, if any ? Thanks for your help.
