Performance overhead

[CommunityUser]

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.

Production mode.
