Is providing more auth for certain T code can cause more proccesing time

Question

Hi All
Is providing more authorization access for certain T code can  cause more time to process the same Tcode.
E.g In our project scenario
There are two users A and B, both have the acces of t-code ML81.
When A is executing T-code ML81 its taking time around 45 second
while it's taking only 2 second when B is executing(Both users executing there task on same system).
Here User A  has more authorization for the objects called by ML81 than user B
Thanks & Regards,

Perhaps a trace is on?
Check St01, st05 and St11.
Normally more auths cause performance improvement. This is at least noticably true in asset accounting reporting.
Another thing worth checking is performance expensive customer exits and enhancements which might apply to some users (user check tables) or be authorization dependent or dependent on what is selected.
In Sm50 you will be able to see what is hanging or taking so much time.
9 times out of 10 it is an expensive select on a table which is user specific.
