It is the same. I have been testing with http://fabricjs.com//animation 
and https://themaninblue.com/experiment/AnimationBenchmark/canvas/ and 
in all circumstances I see 10-12fps.

The web app is responding to data being sent to it over a websocket 
connection from a backend application. I’ll see if we can create 
something that doesn’t rely on the websocket interface that can be run 
in the browser on its own.
