Hello, I have noticed that working with large collections in the new inspector is noticeable slower than with the old one :( I executed a tiny benchmark that is just inspecting a 1.000.000 objects collection: âââââââââ Smalltalk tools inspectorTool: GTInspector. Transcript show: 'Exp with GT-Inspector: '. Transcript show: [ ((1 to: 1000000) collect: [ :i | Object new ]) inspect ] timeToRun. Transcript cr. Smalltalk tools inspectorTool: EyeInspector. Transcript show: 'Exp with EyeInspector: '. Transcript show: [ ((1 to: 1000000) collect: [ :i | Object new ]) inspect ] timeToRun. âââââââââ And the results were: Exp with GT-Inspector: 0:00:01:04.979 Exp with EyeInspector: 0:00:00:00.381 Are you facing the same issue?
