우리의 성능 테스트에서 우리는 높은 CPU 사용량 (100 %)을 경험했으며 스레드 덤프는 스레드가 JSF 수명주기의 복원보기 또는 렌더링 응답 단계를 실행하고있는 대부분의 시간 또는 xhtml 페이지가 들어있는 jar 파일에 액세스하는 동안 차단됩니다. 차단 된 스레드에 대한 스레드 추적JSF 수명주기 단계 실행 중 높은 CPU 사용량

입니다. 나는 이것을 어떻게 더 조사해야하는지에 대한 제안을 받고 싶다. 이것은 정상적인 행동입니까? glassfish는 자원에 대한 일부 캐싱 메커니즘과 같이 차단 된 스레드를 해결하기위한 대안을 제공합니까?
미리 감사
jar 파일을 압축 해제하는 것처럼 보입니다 ... –
xhtml 페이지는 jar 파일에 있습니다. jar 파일에 액세스하는 동안 너무 많은 스레드가 차단 된 것으로 나타납니다. 이것에 대한 대안? 이것들을 아마도 캐쉬에 넣을 수있는 글래스 피어 설정은 무엇일까요? –
web.xml의 jsf 프로젝트 스테이지가 개발 환경으로 설정되어 있습니까? 아마도 캐싱이 불가능 해지고 jar 파일에 반복적으로 액세스하게됩니다. –
