I have been developing in Titanium Appcelerator from the last 9 months and it is really great tool. However I have observed that its performance on the Android platform has been very slow as compared to iOS. Even a 'Hello World' application is sized around 6-9MB .
I am looking to optimise the applications so they perform well on Android. Kindly guide me on the best coding practices and improvements I need to make in my code to improve the performance
