Struts2 performance issue

I am using Struts2 in my application .it's working fine when there is less number of users. But in real time there are around 3000 requests hiting to the application.And after some time my JVM get crashed.I checked the thread dump it seems to be lot of thread blocked while executing the OGNL expression.

And the CPu utilization is always around 130% in the pick times.Please suggest me what will be the best approach to run stuts2 application in highly scalable enviroment.

  • Let's see this, the default setting for struts.ognl.enableExpressionCache

### Caches parsed OGNL expressions, but can lead to memory leaks

### if the application generates a lot of different expressions

struts.ognl.enableExpressionCache=true

  • Or try optimize your Struts2 application by instructions in Performance Tuning.
  • Or monitoring your Struts2 application with Java Melody, Struts2 action can be monitored by add an interceptor.

lately there has been a lot of performance improvement with OGNL so just specify the Struts2 version
