Top ten Tomcat config tips

Tomcat Running in Windows Service

This will help you.

[Budi Kurniawan]

It doesn't offer configuration tips. Rather it teaches how to write your own components. It is not impossible to write a module that can improve performance.

For example, there are four types of containers: Engine, Host, Context, and Wrapper. Every HTTP request for a servlet/JSP page goes through these four. If you know that your Tomcat will only run one application, you can create a Context module that does not need a Host or an Engine. That way, the connector will pass all requests directly to the Context.

Will it improve performance significantly? Or just less resources are used in Tomcat? Could you explain more about this issue so that we can get knowledge how to get the highest performace from Tomcat...

Thanks a lot for your answer...

I think, Speed of starting tomcat server depend on
1. Number of library in common/lib and server/lib
2. Number of web application has been deployed in tomcat

Somkiat Puisungnoen , we use tomcat 4 & 5 to run only one application which we are developed..and we need to test it out for compatible

but the speed still preferable in tomcat 5

Why tomcat 5.0 faster than tomcat 4.0 ??

Answer ::

You can see detail of GOAL of Tomcat 5.0 in below ::

Tomcat 5.0 Goals

Tomcat 5.0 looks great so far. It includes support for the Java Servlet 2.4 and the JSP 2.0 specifications, fixes many performance issues, and adds many new features and other improvements. Below we'll look at the two overall goals of Tomcat 5.0, which were implemented as of version 5.0.16.
