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
