Basic 2-page tab-bar... why is there input lag?

[mavorus]

Hello all.

I created a simple two-page tab-bar based little app by following the getting started guide.. from what I am reading, all of the data is loaded in immediately (for both tabs).

However.. there is about a ~800ms lag time between touching a button, and it actually performing the touch.

What is this lag and how can I avoid it?

Since I loaded the entire UI + data at the beginning, shouldn't there be ~0ms of lag between when I push/click a tab-bar button, and the tab-switch animation starting?

Are there some deeper options I need to dive into? Something related to running the app offline?

Please help

AFAIK, This lag comes from ST2 using "clicked" event instead of a faster/native "touchdown" event.

Is there any way to change the events used or is this something out of our control? I can understand some circumstances where click would be good, but in this case, I really want immediate speed..
