Allen, I got a question for you. I can understand the problem in development about having to recompile on every load, however should I need to recompile every time in production? Or can I compile once and save the swf to be distributed to the clients?

I don't know of and don't think there's any real recommended solutions out there, other than "whatever is fastest". - similarly, one thing that helps compilation speed would be to try a different JVM (different version or even a different implementation... it has been quite awhile since my JRun days so I haven't paid as much attention to this, but back then it paid to try out IBMs JVM or JRockit). Garbage collection settings are also helpful to tweak. If you're using mxmlc.exe, the JVM settings are in bin/jvm.config. - the compiler isn't multi-threaded when it is used from the command-line. It is multi-threaded when used via the browser, but only for allowing multiple compilations to happen at once. - one reason the server is slow to start up because it takes awhile for mx.swc and other SWCs to load. This is one reason why compiling from the command-line is slower, since this loading has to happen on each compilation. - I just checked and we aren't doing incremental compilation from the command-line in a way I thought we were. The way is through something called SWOs. As far as I can tell, this doesn't work from the command-line. Because of this, I would recommend setting cache-swos to false in the flex-config.xml used when compiling from the command-line. While this speeds things up when using the server, from the command-line this is just saved a whole lot of information that isn't being used. - you can get a broad idea of where time is being spent through the unsupported, just-for-the-curious setting of "-Dtrace.benchmark" in the JVM arguments. -Brian -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Allen Manning Sent: Friday, August 05, 2005 3:18 PM To: [email protected] Subject: RE: [flexcoders] Re: Fastest Hardware for Flex compilation Eric, Thanks for the background on this. I agree that it does seem much slower than standard mxml page compilation. Any idea if it is multi-threaded?

Of course this doesn't work well via ant (you can use the <http> tag, but there's no easy way to check for errors). - Startup time for the compiler seems farily high. If you hve more than one app to compile, it's better to compile them in one fell swoop (e.g., We compile three flex apps in about the sam time as it take to compile just the largest app app alone!) - Personally we use the incremental server based compilation during daily development and standalone ant based compilation for distribution builds. > > On 05/08/05, Allen Manning <[EMAIL PROTECTED]> wrote: > > > I'm trying to get my flex compilation time down to as little as > possible. > > > We are using mxmlc via Ant to compile our flex code.
