[jboss-user] [Performance Tuning] - Re: Diff response times at different times
There was a typo in my earlier post regarding CPU Utilization. It was around 60-90% during peak load View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4258922#4258922 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4258922 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [Performance Tuning] - Re: Diff response times at different times
Thanks Peter For your excellent support. During the load test run, I saw that the CPU utilization is around 60-70% I'm setting the PermGen Size to 512m with the params -XX:PermSize=64m -XX:MaxPermSize=512m If I donot set this, I'm quickly getting Out of Memory Permgen Space Error. If I can't increase the heapsize beyond 1700MB(including permgen), Does that mean 2GB/4GB/8GB RAM will not make much difference? If garbage collector is not the culprit for the difference in response times at different intervals, I wonder what else could be the reason...? Will clustering of JBoss help me in meeting the SLA? If yes, can I try the software clustering(with out adding any other hardware), or I have to go with Hardware Clustering only?

Please pardon me for my poor excel skills. The csv files for the tests are here 1. Without setting young size http://new.flyupload.com/files/view/rwy3laQamtpju9Ok1ZH9 2. With Young size setting http://new.flyupload.com/files/view/JP8mCuSxAOH8VTIGWJEj What is meant by think time? My Performance test run is done around for 8 min Where in first 2 min, no. of users slowly ramp up and then steady state is maintained for 5 min and then the no. of users will be ramped down in 1 min Though my RAM is 4 GB, unfortunately, If I am going beyond 1124 MB of heap, I'm getting some error saying that cannot allocate that much heap and the server is not getting started. I'm running I am running JBoss 4.2.3 on Intel Xeon CPU, E5405 @2.00 G.Hz,3.99 GB RAM.

[jboss-user] [Performance Tuning] - Re: Diff response times at different times
I tried with the below JVM Settings : set JAVA_OPTS=%JAVA_OPTS% -Xms1024m âXmx1024m âXX:NewSize=300M âXX:MaxNewSize=300M âXX:SurvivorRatio=32 âXX:+UseTLAB âXX:TLABSize=64K But this settings didn't work well for me. With this setting, I observed that the response time is increased even more.

[jboss-user] [Performance Tuning] - Diff response times at different times
We have a strict SLA requirement that the reports should be displayed in 1 min max for a load of 500 users We are running a load test of 500 users on the application. We are getting different response times in different time intervals. The deviation is from 1 min. to 2 min. I want to understand why the application is giving huge diff. in response times at different time intervals. 1. Is it some thing because of garbage collection? If yes, how to analyze it? 2. Is it because of any memory leaks in the application? If yes, how to analyze it? Can you please help me regarding this? I'm setting the JVM Parameters Xms, -Xmx both to 1024. All the other parameters I'm leaving them as they are in \bin\run.bat View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4258512#4258512 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4258512 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
