Please use this forum to report your experiences with the Ext JS 4.1 Performance Preview release (see the blog post for full details (http://www.sencha.com/blog/ext-js-4-1-developer-preview)). We're especially interested in hearing what kinds of performance impact you see from the 4.1 preview and if you had to change any code to get your application to launch correctly

It would be very helpful, if you have performance issues, to include an example that mimics your particular component configuration. That way we might be able to offer suggestions or do some profiling on our side to see what we can do to further optimize the layout system in your real-world applications.

Now that we are in Beta, performance and compatibility are both of primary concern. If you have to change code for your app to run in 4.1 Beta 1, please let us know. Especially if the changes are not related to anything already explained in blog or forum posts.
