Caching edit methods

There was a great improvement done to the form datasource caching in AX 2009 - it is possible now to cache not only display methods but edit methods too. The caching of the edit methods can be performed in the same way as caching of display methods - by using FormDataSource.cacheAddMethod() method.
Despite that great improvement a lot of forms in AX 2009 haven't consumed it. So if you are looking for a solution to speed up existing AX 2009 form, edit methods that are not cached is a good place to look at.
