1. An Interactive Java Profiler for the F2F Computing Framework Vladimir Škarupelov

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

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

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

5. 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

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

7. Profilers hprof Eclipse TPTP project NetBeans Jprofiler jmemprof JIP Profiler4J

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

17. 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
