[jira] [Commented] (WW-3580) Critical performance issue in production environment as thread dumps are leading to OGNL 3.0 thread blocking! Website could be backed out!

    [ https://issues.apache.org/jira/browse/WW-3580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13090191#comment-13090191 ] 

Alessio Cicioni commented on WW-3580:
-------------------------------------

Is someone working on this? 
We are facing the same problem with Struts 2 (2.1.8.1) in a production environment with heavy load (thousands of contemporary users). 
We changed the OGNL library (using OGNL 3.0) in the STRUTS distribution. The performance are better, but the problem is still there when there are more than 300 contemporary users.
Is there a plan to resolve this issue? In which version and when such version is planned to be released? 
Thanks
