There is a bug reported [ LPP-4115 ] which has bitten several people, where apps which try to load a large number of images in SWF simultaneously either lock up or time out some of the requests.
The SWF runtime has a limit , defined in LzLoadQueue.maxOpen, on the number of requests allowed to be queued, (limit is applied to both media and data requests). I set up some experiments with an app which loads 64 images and 100 data requests, back to back, and tested it the following browsers The image requests went to a jsp page which added a 100 msec delay to each request before returning an image. A similar mechanism was used to add a one second delay for the data requests. Windows FF 2 IE 6 IE 7 Mac OS X : Safari (not sure which version at the moment) Raising the maxOpen limit to infinity led to some errors in loading on IE6. Setting maxOpen to 10 did not cause any errors in this test however. It also noticably increased the performance for loading of images. I should do some more experiments, but it seems like we ought to bump up the default value for maxOpen, to fix the reported bug, and to increase performance of simultaneous image and data load requests in SWF 7/8. -- Henry Minsky Software Architect [EMAIL PROTECTED]
