Latency Analysis & Optimization Questions

Understanding and reducing response time across the request path, including tail latency, latency budgets, and critical-path analysis. Covers where latency accumulates (compute, I/O, serialization, network hops, queuing), percentile-based reasoning (p50/p95/p99), and targeted techniques to shave the dominant contributors. Focuses on end-to-end latency as an engineered property rather than an incidental one.
