Hi,
I want to calculate the total time a site spent loading images using the JSON API.
My plan is to loop through the median->firstView->requests node, isolate the images and sum the image load time from one of the metrics in there, but there are a number relating to load time. I just don’t know what to use. I tried all_ms, but that actually generated a load time greater than the page load time.
Thanks.
"load_end": 947,
"ttfb_start": "854",
"ttfb_end": 947,
"download_start": 947,
"download_end": 947,
"download_ms": 0,
"all_start": "769",
"all_end": 947,
"all_ms": 178,
