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.
