그래서 나는 대신 이것에 대한 테스트를 작성하고 실제 데이터에서보기로 결정했습니다.
테스트 범례
- Itr : 반복
- Seq : 순차적 접근.
- PrlEx : 병렬 확장-Parallel.ForEach
- TPL : 작업 병렬 라이브러리
- TPool : ThreadPool
시험 결과
싱글 코어 CPU [Win7-32]-VMWare에서 실행-

요약
- 단일 코어 환경에서 실행하든 멀티 코어 환경에서 실행하든 Parallel Extensions, TPL 및 ThreadPool 은 동일하게 작동하며 대략적인 결과를 제공합니다 .
- 여전히 TPL 에는 쉬운 예외 처리, 취소 지원 및 작업 결과를 쉽게 반환하는 기능과 같은 장점 이 있습니다 . Parallel Extensions도 또 다른 실행 가능한 대안입니다.
스스로 테스트 실행
여기 에서 소스를 다운로드하고 직접 실행할 수 있습니다 . 결과를 게시 할 수 있으면 나도 추가하겠습니다.
업데이트 : 소스 링크를 수정했습니다.
