After I instantiate a new session, should I "logout" the session before I "Close" the session once I are done? (I noticed that most of examples would "login" to a repository and then just "close" the session without "logout"?        

//at the beginning       

RepositoryRegistration myRepoReg = new RepositoryRegistration("Empower15", "LaserInvestigators"); 
mySess = new Session();
mySess.LogIn(myRepoReg);

//at the end

mySess.Close();
 

Should I do "mySess.LogOut();" before "mySess.Close();"? What is the best way to improve performance?

Thank you for helping me to clarify this.
