Subject [jira] Created: (WW-3456) Input field tags performance degradation on POST versus GET.

Input field tags performance degradation on POST versus GET.
------------------------------------------------------------

                 Key: WW-3456
                 URL: https://issues.apache.org/jira/browse/WW-3456
             Project: Struts 2
          Issue Type: Bug
          Components: Other
    Affects Versions: 2.0.11.2
         Environment: Operating System: Solaris 10, CPU: UltraSPARC T1 (32 1Ghz proccessors),
Application server: glassfish V2
            Reporter: Tom Rispoli


I have a JSP that uses s:iterator to display a large number of rows (up to 2000), each row
contains input fields displayed using s:checkbox and s:textfield.  When the page is initially
opened (the request is done using an http GET) the s:checkbox tag averages from .0028 to .0033
seconds to run and the s:textfield averages from .008 to .012 seconds.  Once the page is opened
on the browser and the form is submitted (an http POST) then when the JSP renders the data
(same code on the JSP generating html for the same data) the times get much slower.  The s:checkbox
averages from .018 to .008 seconds and the s:textfield averages from .027 to .049 seconds.
 

There is a custom tag that is used on the rows as well, it uses OGNL to get its value but
its performance remains the same (around .0004 seconds) for all requests, so it doesn't appear
to be OGNL that is causing this behavior.
