What is the significance of the "Average Load Event" parameter in the Ajax requests in a Virtual Page Dashboard. PFA image for reference.
Is it related to Ajax Callback method?
The VPs are often correlated to the Ajax calls. The section shows list of all related AJAX calls and the 'Average Load' tells the average of the number of calls made for that registered AJAX over a minute.
"After Load Event" tell the number of such ajax requests that got called after the onload event completed.
Yes, that's document load event.
