Support for Performance Observer is now in Chrome Canary!

What is it? Performance Observer allows you to subscribe to notifications of new performance metrics - e.g. resource timing events when a fetch finishes, user timing marks and measure, etc. In short, you no longer have to poll the timeline for new performance events, just subscribe, sit back, and watch them stream in... \o/

Want to give it a try? Boot up Chrome Canary and...
- Enable chrome://flags/#enable-experimental-web-platform-features
- Reboot Chrome Canary
- Visit demo page @ bit.ly/1OiRS7f
