Why does this happen? Is this spacing between the request blocks?
It's all loading below the other, suddenly, it seems like it's going to be 100 or 200ms, and it starts loading (from 11ms there), and then it takes a bit of time, too, and it starts again. >
Is this from the same graph of this tool? Or do you have some explanation in terms of server or website?
I usually see this well at the end of the requisitions, when it's running out of resources to load.
Ps : I used GTMetrix
