Re: [flexcoders] HTTPService return times Air vs Flash (Solved - Kinda)

It always turns out to be the small things. Turns out that using localhost in the url of HTTPService (or URLLoader) was the problem with Firefox. Replacing localhost with my development computer's ip address removes the delay. Judging from the status bar messages of Firefox when making a call using localhost, Firefox is resolving localhost on every request, resulting in a average (subjective) delay of 250 to 500ms before the request hits the server (which I wrote and can debug/break point). Changing the URL fed to HTTPService to using the IP address resolves the problem. -- Warm Regards, Lee
[flexcoders] HTTPService return times Air vs Flash
Web based flex applications seem to take magnitudes longer to return a result than do Air based application. I've tried with HTTPService and URLLoader components and it is the same. I've created one small air application and one small web based flex app identical. Air app is almost instantaneous while the web page based app (Firefox) takes noticeably longer. My guess is that browser mechanics (security, etc) is the culprit. Any suggestions or comments? Thanks, -- Warm Regards, Lee

I take this back. My mistake and should have checked it before posting, but the truth is that Air applications run from the IDE are magnitudes faster that web page based flex app run from the IDE. When testing response times with the COMPILED web based flex app OUTSIDE of the IDE, the difference was noticeable, but negligent. -- Warm Regards, Lee

It appears that its Firefox (3.5.7) that causes the delay. Two test applications with exactly the same code. One is deployed to AIR and the other to a basic webpage, letting FlexBuilder create the html page, etc. SWF running directly in flash player: - Little to no difference, fast AIR app (either in debug mode or not): - Little to no difference, fast SWF running in Internet Explorer 8.0: - Little to no difference, fast FireFox 3.5.7 - Noticeably slower. Everything including server is running local on my computer (3 Gigs of RAM, Vista 32bit) and just to be sure, I disabled all add-ins and plug-ins for Firefox and the result is consistently the same. Using either a URLLoader or HTTPService to pull down xml, Firefox takes a while longer to send the request to the server, once the URLLoader or HTTPService sends methods have been called, than the other methods mentioned above. The server application is my own Delphi/FreePascal based server so I could set a break point on the socket creation line to see exactly when the server received the request from the flex application. With Firefox (as opposed to Air application, Internet Explorer or running the naked swf file in Flash Player) the time it takes for the server to get the request is significantly longer (1.5 secs on average subjective speed) thus providing an overall and significantly longer delay to process the request from click to response. -- Warm Regards, Lee

Re: [flexcoders] HTTPService return times Air vs Flash
I've been told that Firefox limits the amount of processor power that the flash player plugin is allowed to use. That may be your problem. Perhaps it also limits network usage/bandwidth. I can't confirm this is true but your results seem to point that direction. FYI, FF 3.6 was recently released. Maybe try that to see if they have done anything under the hood to help flash performance. -Jake On Thu, Feb 11, 2010 at 11:08 AM, Lee Jenkins l...@datatrakpos.com wrote: Lee Jenkins wrote: Lee Jenkins wrote: Web based flex applications seem to take magnitudes longer to return a result than do Air based application.
