We recently upgraded from Struts 2.1(don't ask) to Struts 2.5.13 , while the upgrade process was smooth, we are facing some performance issue while JSP is rendering at runtime. This JSP used to load in less then 2 secs before and now it's taking around 40 secs to load. It's a very simple JSP with some text fields and a few select fields. I am just posting a simple select that is taking around 20 secs, I cannot post the whole code because of obvious reasons. The time difference between the two-time statements below is around 20 secs.
