You can probably delete the following from server/lib servlets-invoker.jar ( And remove from web.xml) servlets-manager.jar (Unless you *need* the manager) servlets-webdav.jar # Only keep the connectors that you plan on using tomcat-coyote.jar tomcat-http11.jar tomcat-jk.jar tomcat-jk2.jar tomcat-warp.jar
In web.xml, comment out jsp servlet and remove jasper-compiler.jar from common/lib
If you don't need the manager, admin, to compile jsp (which you don't since they are precompiled), I think you might be able to get away with removing all ant related jars too.

First I want to apologize for another of these mails "what is better jetty vs tomcat' but most of the available resources compare both containers in the environment where they are serving multiple concurrent requests. What I am interested is the container that utilizes as little resources as possible and is the most responsive while running on Pentium III or low-end Pentium 4 laptop with small amount of RAM serving single user. My limited knowledge about both products does not allow me to perform any type of container configuration beyond of lowering maximum number of threads for jetty.
Here is what I have done so far and my results:
Windows XP Professional/Pentium 4 M - 2 Ghz/Tomcat 4.1.24/Jetty 4.2.15/JDK 1.4.1
Prototype application uses XSLT/XML/Cloudscape with no connection pooling
I removed all preinstalled Tomcat web applications except Manager.
I also removed bunch of other files from Jetty, Tomcat and SUN's JDK packages which helped me to create two distributable 20 MB zips for both JDK/Tomcat and JDK/ Jetty.
I deployed a prototype application to both Jetty and Tomcat.
I precompiled all jsp for both Jetty and Tomcat - fortunately they both are using jasper :-)
I have observed that Jetty starts and loads application at least twice faster and uses 25% less memory. The pages were rendered within 1 sec.
I am not using <load-on-startup>. to conserve RAM.
Does anybody have comments on this topic?
Are there any Tomcat specific hints to improve its performance and reduce amount of utilized resources assuming that it is being used by a single user?
Thanks for help, Kris.
