Yes, Con's response was outright rude. OTOH he had made clear that he wasn't interested in that kind of discussion.
However Ingo was obviously down the route of "lies & benchmarks". The point of the scheduler is low end machines, and responsiveness. Ingo posts a benchmark with ridiculously high-end machine, and measuring performance.
I just wish that Con had had the cool head to politely point that if you ask the wrong question, you get the wrong answer.
