[jboss-jira] [JBoss JIRA] (JBAS-9472) Improve the processing time of a request with a large number of parameters.

Improve the processing time of a request with a large number of parameters. --------------------------------------------------------------------------- Key: JBAS-9472 URL: https://issues.jboss.org/browse/JBAS-9472 Project: Application Server 3 4 5 and 6 Issue Type: Enhancement Security Level: Public(Everyone can see) Components: Web (Tomcat) service Affects Versions: JBossAS-5.1.0.GA Environment: Linux, Windows Reporter: Toshio Oya Assignee: Remy Maucherat Attachments: modified-5.1.0.GA.zip, sample-app.zip 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. modified-5.1.0.GA.zip - B2CConverter.java ... replacement of org.apache.tomcat.util.buf.B2BConverter - Parameters.java ... replacement of org.apache.tomcat.util.http.Parameters - LocalStrings.properties ... added a new property file to org.apache.tomcat.util.http.
