Discovering JFR: A Journey into Modern Java Profiling Excellence Symptom: memory usage drifts under real production load. Constraint: profiling cannot degrade latency or throughput. Solution: Java Flight Recorder (JFR) — the built‑in, low‑overhead recorder that captures CPU, memory, GC, I/O, and custom events from live systems with typically under 2% impact. With JFR, production evidence replaces g...
