Spring MVC request is too slow

Question

I have a web app that used Spring MVC framework, Tomcat for 7 for front end that call Websphere for back end.

In some pages I have jsp files that call controllers for inserting or updating data. This work well when I try to send a few data but when I try to send more data the application cant response and goes to timeout. The problem is.. for example when I click on a href to open a page passing input data this cant go in the controller method( or it is very slow). So the problem is not the back end and nor the front end I think. But I dont know what I ve to do.. Any suggestion?

Thnx

Answer 1

1. Try it without debug mode.
2. All heavy logic handling behind controllers should be in async mode.
3. Use performance testing to detect your bottle neck .
