At runtime, we update the entire grid by removing all columns
and adding new ones. The Flex Profiler says the method that does
this needs about 600ms, but when clicking the button, you have to
wait over 3 seconds until you finally get to see the updated
We do however, have the [tincan] function that is consuming
about 70% of our total CPU-time, but could this cause other methods
to slow down? Some Googling tought us that tincan is a function
that has something to do with backend communication using BlazeDS.
We use BlazeDS, but only once to retireve a remoteobject with
necessary data when we start up the Flex application, so is it
normal that tincan still needs so much CPU-resources?
If anybody has any thoughts or input that could help us find
the reasons of our performance issues, that would be much
ADG seems to suffer significant degradation performance

Grouping functions are used.
In my case I had a grouping setup with about 200 records and
performance was really terrible - once I removed the grouping

There are lots of posts with complaints about ADG performance
and many refuse to use it because of this issue.
