Find performance bottlenecks
What you will learn
p99 rising while p50 stays flat = thread pool / connection pool saturation, not general slowness
Throughput flat as concurrency grows = hit a bottleneck. Correlate CPU / DB / network to find where
Latency spikes often correlate with GC pauses, autoscaling lags, DB lock contention — rarely just one cause
