how to improve java performance

[sunjavaboy]

Hi

We have a java application built with Swing applet and Servlet running on Tomcat. Some other features are: it uses Struts and log4j, and ANT for compilation.

How can the application be optimized for better performance. The current application is running fine. But I still think there could be areas of improvement. Areas where compilation process can be improved, memory and CPU usage can be reduced, better error reporting, better database connectivity etc.

Any suggestions are welcome.

It's depend on the implementation you have done pal. Did you found such any code that you think possible to make more smoother than now?

I can dig into the code and find some specific things that can be made smoother. But there should be some common things with java that can be improved upon. I would like to know those.

u talking about the development env....
concentrate on the deployment.
install apache seperately and tomcat seperately and connect them using the modjk.
in apache keep the keepalive flag true.
for tomcat set the heap size.

use jmeter to load test.

Are you directed on me? If so, development process is the most critical point in software industry, is what I believe.

Find the pain areas i,e the usecase/pages which are taking more time.
If you look at the logs,you will be able to figure most of the bottelnecks.
