Description Oleg Besedin CLA 2011-09-27 10:43:22 EDT 
ToolBarManagerRenderer$6.changed() takes up 25 - 30% of the CPU time when opening & closing views.

processAddition() :
parentContext.runAndTrack(new RunAndTrack() {
	@Override
	public boolean changed(IEclipseContext context) {
		record.updateVisibility(parentContext.getActiveLeaf());
		manager.update(true);
		// disposeToolbarIfNecessary(toolbarModel);
		return true;
	}
});

There is also similar MenuManagerRenderer$6.changed(), that seems to be taking up somewhere in the range of 5% - 10%.

The time is currently down to about 10 - 15% which is probably as good as it will get for 4.2.
