I have been experiencing recently how slow a listview is perfoming on iOS (tested on iPads and iPhones, iOS 6).
I thought there was something wrong with my offline web "app" example, but then I tried the lists-performance example (http://jquerymobile.com/test/docs/lists/lists-performance.html), and I was surprised how slow it was performing as well.
The issue is something like the one describe at this topic --> https://forum.jquery.com/topic/possible-causes-of-extremely-slow-keyboard-in-ipad-phonegap-app, but even on the regular browser (no phonegap): "the ipad keyboard sticks and key strokes have a major delay between keystroke character and showing up in the input.".
I don't find a listview THAT slow when scrolling, but when I use the filtering it is super slow.
IMHO, this is a blocker for using jquerymobile for anything that needs a simple filterable listview on such an important platform like iOS.
thanks in advance!
