    Description

      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.
