Performance overhead

Hi all,

I'm performing some load test on a JEE application to evaluate performance overhead related to AppDynamics monitoring.

Infrastructure under test involves 2 JBoss 5.1.2 nodes with sticky session enabled behind an Apache proxy balancer. Each JBoss instance runs on Oralce JDK 1.6.0_31 with these JVM params:

-Xms200m

-Xmx4000m

-XX:MaxPermSize=1024m

-XX:+UseParallelOldGC

AppDynamics instrumentation involves only a dozen of POJO Custom Match Rules (no other types of automated transaction discovery are enabled). Monitoring level on the controller is set to "Production" mode.

Performing test-case (by JMeter) shows up to 10% of performance overhead (degradation in response time) with AppDynamics monitoring agents enabled.

How can I improve overall system performance? Any AppDynamics tuning suggestion?

Thanks, 

Marco

Just to be sure, are you in production or development mode? We have not seen such behavior in our environment.
