----------------------------
Integrated in Struts2-JDK6 #625 (See
[https://builds.apache.org/job/Struts2-JDK6/625/])
WW-3971 adds ContainerHolder to reduce numbers of calls to
getConfiguration() and optimize RuntimeConfiguration class to more thread
friendly (Revision 1436878)
Result = SUCCESS

> Components: XML Configuration
> Affects Versions: 2.3.8
> Environment: apache-tomcat-6.0.32, jdk1.6.0_27, devMode set to false.
> Reporter: Michael Sebastian

>
> 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.
