Two quick notes: 1. Looks like you posted this comment pretty close to when this was posted on HN. It's possible the server was more loaded, as I tried it myself and it wasn't very laggy (though there was a delay, it wasn't nearly the one second you experienced). 2. I copied the example code and ran it locally, and the latency is no worse than, say, an electron app. Better than most of them, to be honest. Likely this was related to server load or network latency or both, because the core functionality seems pretty lag-free.
