I had built an iPad app using Flex 4.6|AIR 3.6 sometime back. Looking at this email, I got curious to see how my app would perform on 4.10.
Agreed! Overall performance in comparatively good. - Popups used to have a delay of 3-4 seconds, but now it just pops up without any delay. - Switching between tabs(for the first time) in a TabbedViewNavigator had a delay of 3 to 4s (based on number of UI elements on each of the tab views). But now it takes 1.5s or less. But size got increased a little: - Compiled size was 9,178,761 bytes using flex 4.6|AIR 3.6 and it is 9,762,490 bytes using flex 4.10|AIR 3.8, which is just fine for me, it not a big issue. However, I came across one issue(which wasn't there in Flex 4.6). I am using a datagrid with a skinClass. If I use a skin class, it shows up a blank datagrid on the screen. But when I remove this skinclass property, it displays the datagrid properly with all data in it. Though datagrid is not optimized for mobile, I am still using it for my app(iPad), as I did not find any scrolling issues. It works smoothly as it works for web.
