I haven't tried NativeScript, but I am curious why it would be slow. Slow JavaScript engine on mobile platforms? Emulation library perhaps is not efficient?

I would appreciate some feedback. I just wrote a Firefox addon to work with a rich web app I am working on, and it would be nice to also provide "native" apps. BTW, most of my client code is Clojurescript; has anyone tried NativeScript with Clojurescript?

I have fairly extensive experience with Titanium, and my impression is that the UI can get very laggy if you are not very careful with the way you generate and manipulate the elements on the screen. Going "over the bridge" (parlance for communicating between the JS and native layers via the proxy) is quite expensive.
