An Interactive Java Profiler for the F2F Computing Framework Vladimir Škarupelov

Agenda SIP Communicator Java F2F Computing Framework Profilers Steps to be done

sip-comm Audio/video Internet phone and instant messenger Supported protocols: – SIP – Jabber – ICQ – MSN – others

sip-comm OSGI architecture Easily extensible by plug-ins activate/deactivate feature open-source

Java F2F Computing Framework Power share plug-in for sip-comm On top of sip-comm Sharing depends on – F2f implementation itself – Job implementation – friends/peers resources

Profilers + – Profilers can provide information about application’s narrow places – Extremely helpful in development – Can be used as monitoring - – Significantly slows down the application

Profilers hprof Eclipse TPTP project NetBeans Jprofiler jmemprof JIP Profiler4J

pure java hooks the classloader "on the fly" connection Open source Profiling made easy

Next steps Set up F2F with the latest version of SC Add Profiler4J plugin Remote invoke of the profiler on a peer Lazy profiler init Look for another improvements

Thank you!
