I'm not trolling here, but do you think this preference of yours not to work with "loud" machines has in any way impacted Linux in scale up large N-way server platforms which are as a rule loud?

I appreciate it's not realistic that you work directly on a 128 core machine beside your desk, and I also find that in the last couple of years there has been some public benchmarks which would suggest that Linux can deliver similar scaling as any other OS out there. But does your day to system for development and testing in any way prevent Linux from not just matching the scalability of existing OSes but far exceeding them?

Just curious.
