There is nothing that software can't fix. Unfortunately, there is also nothing that software can't completely fuck up. That gap is called talent.

Memory Profile of MXML vs AS3 for ItemRenderers

Although using MXML can be quicker to code up it appears that using it for itemRenderers is a lot more CPU intensive than coding itemRenderers in AS3. The Repeater component also seems to hog a lot of memory.

Advice:

try and always you an AS3 Class for itemRenderers rather than MXML. I wonder if Gumbo is going to be any better?
