SQL set noCount on in all query - sql

Question

I have a stored proecdure like below:
#userInput int
as
declare isSuperUser int
declare IDs table(
recordID int
);
set isSuper = select isSuper from [User]
if(#isSuper = 1)
Begin
insert into recordID select * from TableA
End
else
Begin
insert into recordID select * from TableB
End
select * from recordID
And I would like to add "set noCount on" on every query, so the question is: is the performance in store procedureA equivalent to store procedureB?
store procedureA :
#userInput int
as
declare isSuperUser int
declare IDs table(
recordID int
);
set noCount on
set isSuper = select isSuper from [User]
if(#isSuper = 1)
Begin
insert into recordID select * from TableA
End
else
Begin
insert into recordID select * from TableB
End
select * from recordID
set noCount off
store procedureB:
#userInput int
as
declare isSuperUser int
declare IDs table(
recordID int
);
set noCount on
set isSuper = select isSuper from [User]
set noCount off
if(#isSuper = 1)
Begin
set noCount on
insert into recordID select * from TableA
set noCount off
End
else
Begin
set noCount on
insert into recordID select * from TableB
set noCount off
End
set noCount on
select * from recordID
set noCount off

Answer 1

SET NOCOUNT ON prevents the sending of DONE_IN_PROC messages to the client for each statement in a stored procedure. For stored procedures that contain several statements that do not return much actual data, or for procedures that contain Transact-SQL loops, setting SET NOCOUNT to ON can provide a significant performance boost, because network traffic is greatly reduced.

While storedProcedure is executing , there is no point of sending data back to client, setting noCount On increases performance as it reduces network traffic .
In your Store Procedure B you are switching NoCount on to off which increases network traffic.
