Well, I can't explain it, but this morning when I re-installed Flash Builder 11.9, I got the 2 sec time I was expecting instead of the 30 sec I was seeing last night.
Justin, thanks for the heads-up on using the browser's developer tools. I was able to use them for Firefox and Chrome just now and they're pretty useful. Alex, I didn't see any words displayed when the progress bar was shown, but I found this link: http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7e3c.html that explained the default preloader is spark (SparkDownloadProgressBar class), which doesn't include words, but I could use the mx version (DownloadProgressBar) to support text. Thanks for mentioning it! ----- Original Message ----- From: "Alex Harui" <aha...@adobe.com> To: users@flex.apache.org Sent: Monday, October 28, 2013 9:26:29 PM Subject: Re: why first browser loading of Flex app takes so long? The default progress bar has two phases: downloading and initializing. The progress bar should display one of those words. If 30 seconds is happening during the initializing phase, then it means that the SWF is already downloaded and all of the time is being consumed creating, initializing and laying out components. The profiler will show you the where the time is going. -Alex On 10/28/13 7:27 PM, "modjkl...@comcast.net" <modjkl...@comcast.net> wrote: >Not sure if it makes a difference here, but note that I have checked the >"Merge into code" (under Flex Build Path, Framework Linkage), and the >total Main.swf file is 2 MB.
