Dramatically improve site performance
Performance is very poor. E.g. for a page picked at random you are in the bottom 50% of sites in terms of speed according the pingdom speed test. See e.g. https://tools.pingdom.com/#!/dYpCmZ/https://docs.microsoft.com/en-us/uwp/api/windows.ui.input.spatial.spatialp
You take 48 requests (including 21 scripts!) and 1.22MB to show some a site where the valuable content is text.. Speed is critical for technical docs, since you tend to click around so much.
Thanks for the feedback, we are currently looking into how we can improve the performance.

I couldn't reproduce this. Could you share which URL you were accessing?
There is a script on the docs page which is continuously firing a DOM event called "message". "e.data.value" has a value of
Also this site makes many requests to
"https://microsoft.stream1.fyre.co/v3.0/collection/167620738/1484486740677228/" and "https://ct214.dsr.livefyre.com/v3.1/collection/167620738/1484486740677228/?multi=true&jid&siteId=381623&networkId=microsoft.fyre.co&backend=DTH&rlo=0&err=0&to=0&cV=undefined".
One core runts at 100% on this site. I am using Microsoft Edge.
