What does "XHR Load" mean in Chrome Developer Tools?

The output looks like this:

I don't really understand what "XHR Load" exactly means. According to Google reference, "XHR Load" is an event. So, what exactly does it mean that the XHR Load took 3014ms (in total)? Does it mean that the execution of the function triggered by this event took 3014ms?
