While I agree that one may end up in browser deadlock over the size of the report, I think it isn’t really supposed to be used for that. I’d rather use it to check my components, modules - not entire suites. Select a part of your app you want to test, and test just that. If you’ve built your app well, you can probably divide it up into independently testable parts, and this is where this tool really shines, taking an incremental approach to optimization.
