Description

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.
