Performance and conceptual questions


I built a complete real world app in Sencha Touch but on Android, the performance is simply unacceptable (especially the scrolling and the tap delays are cruel). So this should be better with ionic and angular using, right? Or are there any bottlenecks concerning performance, too (escpecially on Android)? What about larger apps?

And another question concerning the technology stack. I understood that ionic is a pure ui framework and angular should do the rest. But the perspective to build all the architecture in order to build up an app workflow doesn’t seem very nice to me. Is there any framework compatible to angular which can be easily used in combination with ionic?

Big thanks in advance.
