> We ported an existing business application from Tomcat 5.5.x to JBoss AS 5.1.0.GA.
> When running the application on JBoss AS, we found that the processing of a POST request with a large number of parameters takes longer than doing it on Tomcat.
> We investigated the cause, it occurred in the processing of org.apache.tomcat.util.http.Parameters class in JBossAS/JBossWeb.
> So, we've created a patch for JBoss AS to improve it.
> We applied this patch to JBoss AS, then the processing time of 10,000 parameters in a POST request is now as follows.
>  - Time of processing request.getParameterMap().
> 	Before:
> 		22,635.0 msec (average of 3 times)
> 	After:
> 		     2.3 msec (average of 3 times)
> We want to incorporate this patch in JBoss AS.
> Using our sample application:
>  1. Build
>     $ cd /tmp
>     $ unzip sample-app.zip
>     $ cd sample-app
>     $ mvn package
>  2. Deploy
>     Please copy the test_war-1.0.war to your deploy directory for your JBossAS.
>     $ cd blank_war/target/
>     $ cp test_war-1.0.war $JBOSS_HOME/server/<profile>/deploy
>  3. Test
>     Access the url - http://server:port/test_war-1.0/ via a web browser.
>     Press the "click" button in the page.
>     And, press "OK" button on a dialog.
>     The time of processing request.getParameters() is logged to CONSOLE and log/server.log.
>     ex)
>      13:42:43,084 FATAL [SampleTestAction] request.getParameterMap() taken 20467 msec.
> About patch.
