Chrome: `fetch` takes too long
Update:
I changed the API from fetch to XMLHttpRequest and I still see the problem.
According to the console logs the delay is between "readyState 1"(i.e. OPENED) and "readyState 2"(i.e HEADERS_RECEIVED).
Also, maybe it is worth mentioning, that in Firefox it works fine.
I would appreciate a couple of pointers on how to debug why the call to fetch() takes 1 sec in chrome.
According to "network" tab the request took only 12ms. However in my logs and the "timeline" tab the fetch() takes 1.06 sec. (Screenshots below).
Any tips on how to figure out what is stalling the fetch()?

Turns out it was a Chrome bug that has now been fixed in Chrome 54: https://bugs.chromium.org/p/chromium/issues/detail?id=649590#c1
