Currently we have around 5000+ users and 5 million of privilege records exist. ResolvePrivileges() method dealing 5 million records and its took around 6000ms to execute. I have tried refracting this method my Parrallel.Foreach loop but its come around 4500ms to execute.I have tried to club all 3 methods LoadNimUsersWithPrivilegesToPlaybackPortal(),CreateUserPrivilegesObjects(),ResolvePrivileges() into store procedure but there are 2 systems are hosted on different server so its not possible as only way to reach its by WCF so that option also not possible. Only ResolvePrivileges() is directly deals with db which has under my authority. I am thinking of converting Dictionalty "Dictionary<int, UserPrivileges> users" into json or xml and try to operate from store procedure.Please suggest a better idea if you can have.
