In the document, the Load Time measure is defined as "Represents the total time of a user action". What does it mean? Does it includes the time spent on UEM post calls (sending data from the client browser to UEM servers)? It seems not because I can't see it in Slow third party content section in the User Action Purepath.
Where can I find the user experience configurations to show the slowest calls? Is it 4 seconds threshold?
Based on what you described, the post call won't be included in Load Time since Load Time ends when onload event ends. Is it right?
