Wie konfiguriert man CIFS, damit lokale und Domänenbenutzer schnelle Übertragungsgeschwindigkeiten haben?
Ich habe massive Leistungsprobleme bei der Verwendung von CIFS / SMB / Samba in Kombination mit Benutzern. Dies ist unabhängig davon, ob Active Directory (AD) aktiviert oder deaktiviert ist. Sowohl lokale als auch Domänenbenutzer übertragen Daten sehr langsam. Als Gastbenutzer ist alles in Ordnung.
Ich kann jedoch nicht herausfinden, was den Engpass für authentifizierte Benutzer verursacht. Und wie konfiguriere ich Samba, um das Problem zu vermeiden?
CIFS-/SMB-Übertragungsgeschwindigkeiten
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)
