Anyone have any problems with iPhone slow rendering?
i'm writing an app but finding the more complex that it gets the slower it is to render on the iPhone. Once it renders the performance is excellent but it's just mind boggling slow to render.
I've done a lot of testing on the various parts of the app and Parsing and executing the JS all seems fine but rendering (drawing) the elements in the browser is very slow. I'm not sure exactly where the JS ends and the rendering starts but it seems that it's build the background objects and parsed and built the Xtemplates.
I have an iPhone 4 and 3 and a Samsung Galaxy I and an HTC Desire (both running Android 2.2).
the same app on the Androids takes about 5 seconds to load and on the iPhone 4 it is taking over 30!!!! the iPhone3 over 40.
I expect the iPhone 3 to be slow but it seems mental that the latest iPhone is struggling so much when compared to these older phones. Is it possible that the
in the meantime i'm going to look deeper into the sencha src code to see if i can see if this is actually JS or to see exactly when the browser is told to render.
anyone have any thoughts or benchmarks times of their apps?
