Profiling Procedure

• YourKit 12 (committers are eligible for a free Open Source license)
• To profile fcrepo4 with mvn jetty:run (as opposed to profiling a deployment the webapp in another container)
  
  • Determine the path to your profiler agent library (platform dependent), see: http://www.yourkit.com/docs/12/help/agent.jsp
  • include -agentpath in your MAVEN_OPTS, for example, on OS X:
    
    • export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=128m -agentpath:/Applications/YourKit_Java_Profiler_12.0.5.app/bin/mac/libyjpagent.jnilib=delay=10000"
  • cd fcrepo4/fcrepo-webapp
  • mvn jetty:run
  • YourKit should now display "Launcher" application as "Ready for profiling".
