Profiling Eclipse RCP applications with Eclipse TPTP

I believe approx. one or two years ago I tried to profile an Eclipse RCP application with the Eclipse TPTP project. I believe at this point in time profiling an RCP application with TPTP was not possible.

I learned from Eugene Chan that the TPTP release which is part of Eclipse Galileo allows to profile Eclipse RCP applications.

I suggest you give it a try, it is as easy as profiling a standard ;-) Java application.

You find an updated description here: Eclipse TPTP Tutorial.

Thanks to Eugene Chan, Paul Slauenwhite and Kathy Chan from the TPTP team for feedback on the article.

  1. Hi,

    Don’t you have any isssues with performance running TPTP? (yes TPTP is here to track down this ^^)
    When I tried to use TPTP with my RCP appliction, only launching my RCP app tooks 30min… Is there some configuration that I may be miss? or is it “normal”?

    Each time when I tried TPTP I chose another tool for profiling :) But from time to time I try it again and have the same results :) Now I use YourKit profiler.

  3. Lars Vogel says:

    @Aurelien Profiling my RCP app also took longer. But you can use the filter to profile only the classes you are interested in.

  4. Ok, I never used the filter as I never explore really TPTP as it was so slow. Thanks for the advice :)

  5. Lars Vogel says:

    @Aurelien: I also learned this feature from Eugene. Very cool and speeds up quite a bit the profiling process.

  6. Ben Vitale says:

    I have also had trouble with the scalability of TPTP when profiling an RCP app. I also ultimately chose to use YourKit, which does not appear to suffer from the same scalability problems.

    I did change my filter in TPTP to only do execution time analysis on com.mycompany.*, but apparently that is still too much data, because when I start to profile, and the Profile perspective shows it has recorded about 1gig of data, it comes to a grinding halt and I have to kill Eclipse and the app that was launched.

    When I use YourKit, I launch it standalone (not within Eclipse), and simultaneously launch my app with the -agent parameter, then connect the two together.
