Adding a new item to the todo-example shows a noticeable delay until the new item appears in the list. (Maybe 0.3 - 0.5 seconds).

My configuration:
Windows 7
Firefox 8.0
3-year old Thinkpad.
In chrome, the delay is shorter, but still noticeable. I tried to profile in Firebug, but I couldn't get any obvious results/bottlenecks.

I'm mentioning it, because the todo-app is probably what lots of people will look at when comparing js-frameworks. So far, ember's (and knockout's) todo-apps are definitely slower than backbone's, which might put some people off.
