Struts2 request-> response time is considerably increased.

Struts2 > 2.3.1.2 is remarkably very slow when we compare it with struts2 2.3.1.2

I found struts2 application is getting slow when we use

<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter</filter-class>

When i use StrutsPrepareAndExecuteFilter the performance is pretty good like before. But it will mess up the sitemesh integration.
