Your question is Optimizing Code to Reduce 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).
Describe a time you had to optimize a piece of code that was causing system latency. Explain how you identified the bottleneck, decided what to change, validated the improvement, and communicated the result. Focus on your individual contribution, the trade-offs you considered, and what you learned.
