Why does this “Slow network detected…” log appear in Chrome?

Question

I noticed this info log began to appear in Google Chrome Dev (Version 55.0.2883.18 dev) and I can\'t imagine why.

Slow network is detecte

Answer 1

Updating to the latest version of Chrome (63.0.3239.84) via Help -> About fixed it for me.

(actually, I did had to switch to Offline and back to Online in the Network tab of developers tools to make the last errors go away.)
