• Find the bottleneck from evidence: profiler flame graphs, database query statistics, thread and pool metrics, resource saturation (USE: utilization, saturation, errors).
• Fix the largest one, re-measure; the next bottleneck then shows.
• Typical order: remove unnecessary work (N+1 queries, missing index), then caching, concurrency, and only then micro-tuning.
• Amdahl's law: removing a part that is 5% of the time can at best gain 5%.
