Hi,
The GTInspector just became a performance analysis tool, too. You can simply inspect a MessageTally and you get several useful views that help you identify performance problems.
You can read a more detailed description here: http://www.humane-assessment.com/blog/assessing-pharo-performance-with-gtins...
As an appetizer, I attached a screenshot with a Graph-ET chart (thank you Daniel Aviv for developing this engine).

To play with the code, you can just work in the latest Moose 5.0 image: https://ci.inria.fr/moose/job/moose-5.0/lastSuccessfulBuild/artifact/moose-5...
Please let me know what you think.
Cheers, Doru
