> While load testing a web application on Tomcat 6 using Struts 2.3.8 version.
> devMode is set to false.
> Found lot of BLOCKED threads in this method:
> com.opensymphony.xwork2.config.ConfigurationManager.getConfiguration()
> This is causing high CPU usage for the application. also found that
> com.opensymphony.xwork2.config.ConfigurationManager.conditionalRelad is
> taking time which causes getconfiguration (synchronized) to queue up for
> processing.
> This happens when concurrent users are above 100.
