Manjeet Singh, Lead Technical Consultant at Perficient, recently wrote a blog post about issues relating to a slow People Picker in SharePoint.
Have you experienced problems with People Picker taking too long to find a user? Almost a minute or may be more. Does your SharePoint Environment functions with multiple domains?
One of the reasons for sluggish behavior of people picker is the People Picker property called “SearchActiveDirectoryDomains” which usually scopes the entire AD with its sub trees and trusted AD’s while searching for the users account.
In his post, Manjeet details the step-by-step process to fix this issue. You can read the entire blog post here.
