Checklist

•Reproduce workload under representative traffic and datasets.
•Capture traces, flame graphs, and key metrics (latency, throughput, memory).
•Identify top offenders and quantify potential wins.
•Evaluate caching, batching, and algorithmic options with trade-offs.
•Recommend rollout plus monitoring signals to confirm impact.

Prompts

•"Break down the request lifecycle and pinpoint where time is spent."
•"Design a canary or feature flag strategy to derisk the optimization."

Resources

•Profiling quickstart (Chrome DevTools, pprof, perf).
•Performance budget template.
