설명

각 세대에 대해 가비지 수집기는 해당 세대에 할당에 대한 임계값을 설정합니다. 할당 크기가 이 임계값을 초과하면 해당 생성 시 가비지 수집이 트리거됩니다. 예를 들어 2세대의 임계값이 20MB(즉, 20MB가 1세대 컬렉션에서 유지되고 2세대로 승격됨)이고 20MB 이상이 1세대에서 살아남았고 2세대로 메시지가 표시되면 다음 가비지 수집이 2세대 수집으로 시도됩니다. 마찬가지로, 큰 개체 힙(LOH)의 임계값이 20MB이고 앱에서 20MB 이상의 큰 개체를 할당한 경우 다음 가비지 수집도 2세대 컬렉션으로 시도됩니다(LOH는 gen2 가비지 수집에서만 수집되기 때문에).

및 largeObjectHeapThreshold 임계값은 maxGenerationThreshold 전체 가비지 수집이 발생하기 전에 알림을 받을 정도를 미리 제어합니다. 임계값이 클수록 알림과 다음 전체 가비지 수집 사이에 더 많은 할당이 발생할 수 있습니다.

런타임에서 전체 가비지 수집을 수행 하 고 사용 하 여 해당 컬렉션을 우회 하려고 할 때 알림을 받으려면 요청할 수 있는 공용 언어 런타임에서 전체 가비지 수집이 나쁜 영향을 애플리케이션의 성능에 있는 경우 컬렉션을 직접 실행 (사용 하 여를 Collect 메서드) 조건이 여전히 유리할 경우. 가비지 수집 일정을 직접 변경하는 것 외에도 다음과 같은 시나리오에서 전체 GC 알림이 유용합니다.

전체 가비지 수집의 접근 방식을 모니터링하고, 가비지 수집이 다가오고 있다는 알림을 받으면 라이브 데이터 크기(예: 일부 캐시 항목을 해제)를 줄입니다. 결과적으로 가비지 수집이 발생하면 더 많은 메모리를 회수할 수 있습니다.
일부 통계를 수집할 수 있도록 전체 가비지 수집 완료를 모니터링합니다. 예를 들어 라이브 데이터의 크기를 알 수 있도록 GC 완료 시 힙의 크기를 측정할 수 있습니다. (전체 GC 후 힙은 가장 작은 크기입니다.)

전체 가비지 수집을 나타내는 항목에 대한 자세한 내용은 가비지 수집 알림을 참조하세요.

가비지 수집 알림을 등록할 때 전체 가비지 수집이 가까워지고 완료될 때 알림을 받을 수 있습니다. 이 패턴은 운영 체제가 메모리 부족 알림을 모니터링하는 방식과 유사합니다.

다음 지침에 따라 매개 변수 및 largeObjectHeapThreshold 매개 변수를 maxGenerationThreshold 지정합니다.

임계값이 클수록 알림과 전체 가비지 수집 간에 더 많은 할당이 발생합니다.

임계값이 클수록 런타임에서 다가오는 컬렉션을 확인할 수 있는 더 많은 기회가 제공됩니다. 이렇게 하면 알림을 받을 가능성이 높아집니다. 그러나 런타임이 다음 컬렉션을 유도하기 전에 더 많은 할당이 발생하므로 임계값을 너무 높게 설정해서는 안 됩니다.

높은 임계값을 사용하여 알림 시 컬렉션을 직접 유도하는 경우 런타임의 다음 컬렉션에서 회수하는 것보다 더 적은 수의 개체가 회수됩니다.
임계값이 작을수록 알림과 전체 가비지 수집 간의 할당이 줄어듭니다.
