Chrome Devtools ACTUAL data size/transferred


On the Network Tab of the Chrome Devtools I cannot understand the difference between the 2 data values reported (850KB / 14.7 MB transferred). I assume the first value 850KB is data size and the second value 14.7 MB the transferred data. However I am confused.

  1. What is the actual size of the files?
  2. Shouldn't the size of the files equal the size of the transferred values or shouldn't the transferred size (I assume 14.7 MB) be smaller than the actual size of the files (in case the files were compressed)?

enter image description here

The chrome devtools page on resource loading measurements report only one value; so I am confused.


Solution

  • Chrome inspect gives u a bunch of filters such as All,XHR , JS , img. So the amount is for the filtered part of ur data. If you select "All" option in the filter you will find something like 14.7MB/14.7MB
