I have rather complex requirements for access rights, it will end up with lots of groups and users assigned to the node (folder) without inheritng permissions. I wonder will it affect search and retreival performance? It seems to work fine in dev environemnt with small number of folders and limited number of groups but I would like to know what happens when repository starts to grow? I am worried that permision evaluation may impact performance.
Is there any general recomendation to stay on the safe side?
You'd better re-use your permissions and use inherit and use groups as much as possible and Don’t setup specific two much permissions for users or groups at a folder level. it will downgrade search performence
