Single data point by the looks of it but dang, TCP RTT from North Korea to one of our CDNs is slow AF, 1.53 seconds.

For comparison, the mean values around Europe are in the order of 25-30ms.

TCP RTT for a BBC telemetry service by country from end user/client to closest CDN [1] PoP.

Larger, redder circles are slower/worse.

This neatly illustrates the global web performance divide.

TCP: Transmission Control Protocol
RTT: Round Trip Time
PoP: Point of Presence

[1] I can't name the CDN, sorry, corp/competition rules.

The Web Performance Working Group published a First Public Working Draft of Long Animation Frames API. This document defines an API that web page authors can use to detect presence of "long animation frames" that monopolize the UI thread for extended periods of time and block other critical tasks from being executed - e.g. reacting to user input.
