Subject Re: Flex 3 to Flex 4 Performance degradation
Date Fri, 24 Aug 2012 09:25:54 GMT
IMHO, performance is very important, but for the main use cases where flex
is choose over other technologies (IT applications, form applications,
large scale apps,...) the benefits introduced in Fx4 are critical. So we
need to get better both of them (performance and ease of development).

One of the things Alex comment in the blog post (order or addChilds in
generated as3 code from mxml) seems to be something that could be done
nowadays modifiync the mxmlc, isn't it?
