몇 가지 조인이 포함 된 쿼리를 실행하고 QA 환경에 사용되는 SQL Server 인스턴스에서 약 4K 개의 레코드를 반환합니다. 로컬 개발 컴퓨터에서 쿼리를 실행하고 SSMS를 통해 DEV 환경에 사용되는 SQL Server 인스턴스에서 쿼리가 즉시 반환됩니다 (0 초). 그러나 QA 환경의 SSMS 쿼리 창에서 동일한 쿼리를 실행하면 약 50 돌아올 초. 쿼리가 엔티티 프레임 워크 6. .NET 응용 프로그램에 사용 된 코드를 사용하여 .NET 응용 프로그램에서 생성되는 것은 다음SQL Server : select query timeout

위의 코드에 의해 생성 된 SQL 쿼리는 다음과 같다
데이터베이스 구조 (테이블)와 데이터가 모든 로컬, DEV 및 QA 환경에서 동일 할 때 QA 환경에서 실행 속도가 느려질 가능성이 더 큰 원인은 무엇입니까? 이 쿼리를 실행하는 데 걸리는 시간을 어떻게 단축 할 수 있습니까? 인덱스는 세 가지 환경 모두에서 동일합니다. 서버와이 경우 대부분의 아마 당신이 품질 보증 서버의 실행 계획에 조인 최적화하지 않는 것을 발견 할 것이다
, 당신은 그것의 실행을 최적화하기 위해 QA 서버에 update statistics를 실행해야합니다 모두
QA 서버에서 통계를 확인했거나 업데이트했을 가능성이 있습니까? 아마도 이것들은 큰 데이터로드 나 그와 비슷한 것 이후에 동기화되지 않습니다 ... –
서버의 SQL 버전은 무엇입니까? 세션 번호는 개입니까? 재 컴파일로 확인 하시겠습니까? 결국 결국 두 버전의 실행 계획을 자세히보고 싶습니다. –
