We've seen some large memory footprints in our AJAX-heavy applications, but I've also heard horror stories on Flex applications too. There is some massive competition going on right now between Mozilla, Apple and Google to improve the JavaScript performance in browsers, so the situation is only going to get better. Adobe is the only entity behind Flash, so I don't see it getting the same number of braincells burned on it. -Tim Hi David,

However, if you try using many ExtJS components in a large app you will quickly see your browser consume more and more memory. I am developing a large ExtJS app and after 5-10 minutes of use the browser is taking up over 500 megs of memory. Many threads on the ExtJS forums post similar problems and unfortunately they don't all appear to be getting fixed. This is something you would not have to deal with as much using Flex. The plugin controls the memory management and you don't have to rely on different browsers doing different things and causing memory leaks. There is no question ExtJS has some wonderful components.
