Memory Profile of MXML vs AS3 for ItemRenderers   no comments

Posted at 1:03 pm in Flash/Flex

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?
