RE: Performance Question - Authority check rate exceeded gui

John,
this is most likely a big part of your problem.
When you have _any_ user with less than public authority to an object,
it causes a flag to be set on that object which causes extra checking.
What happens is when someone tries to access an object, the system
checks public authority to determine if it is adequate for the desired
operation. If it is they are allowed, if not it checks other
authorities.
(I forget the order it walks through.) If the flag is set, when the
public
authority is checked the system notices that _someone_ has less than
public. It then has to check if that user is one of those with less
authority.
This side trip occurs on each object access and will slow things down.

Your suggestion of using a Primary Group for your users and tightening
up public while granting primary group authority to production objects
is good and should help your performance some.
