All,
I am seeing some incredible lag while using a couple of simple
panels and a complex ADG. While I love the flexibility and power of
Flex/AS and the ADG, I really need to overcome these performance
problems or the project will sink.
My ADG has approx. 100 columns with approx. 200 rows, in a grouping
collection that contains approx 30 groups.
I suspect the lag I am seeing has to do with the redrawing of the
rows. Whenever I scroll or collapse/expand the nodes, it takes between
1/2 to 1 second for the action to complete. And this isn't even a very
large dataset...we have some that have a few thousand rows. I haven't
used any item rendering (yet) that would slow the speed down, though I
have two columns that have style functions attached. All in all, this is
about as close to display the raw data as I can get.
I have spent some time with the profiler and performance monitor and
it appears the the code is sound and without memory leaks. I have also
gone thru to refactor poorly designed code and remove unnecessary nestings.
So my initial questions with this admittedly somewhat vague problem are:
1.) Is there a way to turn off the animations and would doing so
help with the speed?
2.) Has anyone else faced this same dilemma and how did you
overcome the problems?
Thanks,
Adrian
