I am developing an iPhone web app that frequently has to hit my website via a jQuery AJAX call for data. Let's suppose that the data consists of statistics for a selected metric for a selected geographical area. Even when a user reselects the same combination of metric and area, the web app refetches the data.
I've considered the idea of saving the statistics for a given metric & area combination, and then producing those statistics from memory instead of fetching them again. My concern is that I don't know how much memory is available for this type of thing in JavaScript on the iPhone. Possibly I can make up a test that will help me get an idea, but that won't conclusively tell me the minimum amount of memory that I can count on at all times. The main reason I would "cache" the data in this way is to improve performance on an old (slow) iPhone. On a new iPhone, this probably wouldn't be worth the effort. Does anyone know how much memory we can use on the iPhone in a web app? What happens when you run out of memory? Any other thoughts?
