I noticed that ext-all.js is a lot larger in ExtJS4:
4.0 Beta1: 951KB
Is this (close to) the final size or is there still room for improvement in the final 4.0 release?
Our ExtJS apps are noticeably faster than "traditional" apps that generate HTML on the server, _except_ for the initial loading time. On slow network connections this has already been an issue in the past. It would be a shame if the problem becomes so much worse in a new ExtJS version.
