3.3 M6 + org.eclipse.jdt.core_3.3.0.v_749.jar
sun jre 1.6.0_02-ea

- installed europa on top M6
- imported all plugins / features in a new wks (1000 + projects)
- show view --> Progress
- Open Type Hierarchy --> open type core.runtime.Plugin

--> the type hierarchy is (very) long to build and display

Took Yourkit CPU snpashot (to be attached HTML file) and found that most of the CPU time is spent in JarPackageFragmentRoot class

Closing as VERIFIED for 3.3M7 since the type hierarchy performance tests are between 13% and 30% faster than 3.2.
