로컬 및 도메인 사용자가 빠른 전송 속도를 갖도록 CIFS를 구성하는 방법은 무엇입니까?
사용자와 함께 CIFS/SMB/Samba를 사용할 때 엄청난 성능 문제가 있습니다. Active Directory(AD) 활성화 또는 비활성화와는 독립적입니다. 로컬 및 도메인 사용자는 데이터를 매우 느리게 전송합니다. 게스트 사용자는 괜찮습니다.
그러나 인증된 사용자에게 병목 현상을 일으키는 원인을 알 수 없습니까? 그리고 문제를 피하기 위해 삼바를 구성하는 방법은 무엇입니까?
CIFS/SMB 전송 속도
User ----------- write ------------ read
Root ---------- 21.3MB/s -------- 21.8MB/s
Domain -------- 19.7MB/s -------- 19.4MB/s
Guest----------105.1MB/s ------- 101.2MB/s
(Root via AFP 109.7MB/s ------- 108.9MB/s)
