The UI performance feels snappy to me, and opening up threads or going to commonly used pages feels about as fast as Gmail. From watching the performance w/ network tab open things happen in around 300 - 500 ms, which is inline w/ Gmail as well.

_Opening_ app.hey.com is a different story, and is far faster than opening a tab to gmail. I often wait for Gmail while staring at a blank tab as it loads, even one a fast broadband connection. Using Gmail over spotty broadbad, say while traveling, often leads to dropping down into "simple HTML mode".

Hey loads up very, very quickly, which isn't surprising given how small the bundle of html/js/css you are pulling down is.
