في هذا الدرس

pick a collector for a latency or throughput goal.

الموضوعات المخطط لها

• Parallel GC: maximizes throughput with stop-the-world pauses; good for batch jobs.
• G1: region-based, targets a pause goal (-XX:MaxGCPauseMillis); the default in modern JDKs; a sound general choice.
• ZGC: concurrent, very short pauses even on large heaps; trades some throughput and memory; generational mode in newer JDKs (verify version before recording).
• Choose from a requirement (p99 latency, throughput), then measure.
• Do not switch collectors without a baseline.
