How to identify ConfigMgr collections that take long to refresh

I’ve put together the below PowerShell script this week to identify collections in ConfigMgr that require the longest time to refresh. If you ever experience a decrease in ConfigMgr collection update performance, you might want to run this script to find potential collections that have a long refresh duration.


Thanks to Roger Zander and Claude Henchoz for the SQL query to find these collections.
