Your question is Optimizing Network Stack for Latency. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How do you optimize network stack settings for high-throughput, low-latency applications? Explain how you would measure the current bottleneck, choose kernel and NIC settings, validate the changes safely, and preserve required security controls. Address CPU affinity, queueing, interrupt handling, socket buffers, connection behavior, and rollback criteria.
