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
