Hi Jack, I'm not convinced this can be easily generalized into a framework feature. First, IIRC, the player does not allow workers to modify display objects. The workers could compute some information the display objects might need, but the overhead of data transfer between the workers and the main rendering thread is likely to overwhelm the advantage of the worker threads in most cases.
Fundamentally, the DG rendering resolves to manipulating an m-by-n grid of components/renderers based on a data set. You don't need to modify DG code to show us it can work, you can simply take a bunch of components, tie their values to some data and put them in a Vgroup and show us what computation can be moved to workers that would speed up rendering of that set of components. -Alex On 9/22/13 10:59 PM, "Jack Yu" <j...@appcomputing.com> wrote: >if we can have multi-threaded workers for DG rendering, for example, if we >can have 2 or 4 workers in DG rendering, we can split all the cells into >multiple groups, and render them concurrently. > >currently, the DG rendering has only one thread, which will process all >the >cells sequentially, one after the other... that causes the slow >performance. > >-Jack > >-----Original Message----- >From: Justin Mclean [mailto:jus...@classsoftware.com] >Sent: Sunday, September 22, 2013 10:03 PM >To: dev@flex.apache.org >Subject: Re: Next release of Apache Flex > >Hi, > >> horrible bug on day light saving time handling for year 2006 and earlier >That's likely to be a Flash Player bug not a BlazeDS one - at a guess.
