First of all the flex framework is stored in the flash cache, so clearing out your cache often ( I have my browsers set up to clear the cache when I close the program ) does not clear the flex framework RSL. The flash cache needs to be cleared from the Flash Player™ Settings Manager. If you only have one app that uses very little of the framework, you still probably use quite a bit of the framework but I could see how using RSLs might seem like a waste of your time. You really have to compare the sizes between the separate files and a single file then think about how often people will reuse your app ( and any other app that uses the same flex framework RSLs ) then decide what makes the most sense for you. Now, if that is still to heavy you can make a pure actionscript project and use a separate GUI framework such as ASwing ( http://www.aswing.org/ ). Then you wouldn't have to worry about as much overhead. Something like that might be better for a slideshow anyway ( depending on what you are trying to build ). If you are comfortable with actionscript then this is a great way to come up with something that doesn't look like a flex app. I hope some of that information helps you out. Thanks for the comment Joe.

I would love to know if there is a way of making Flex streamlined like Flash. I decided to recreate a slideshow utility using Flex so that I had access to the much nicer and easier framework tools. Unfortunately, if the framework has not yet been cached, this means a file that was originally about 50k is now multiple files, adding up to about 2MB.

Caching is all well and good, but no substitute for streamlined frameworks. I just wish I could take the bits I was using (mx:Tile, s:Group etc) and strip the rest. There are a lot of people out there like me who clear out their caches on a regular basis, and sitting there waiting for a plain slideshow to load when it originally sat in a tiny few K is pretty terrible.
