Long time to launch a small flex application?

Question

JavaScript

It was required to send files by an ajax. In order not to waste time first on collecting a bunch of javascript crutches to get a cross-browser solution, I decided to convert the files to base64 with a small flash drive and send them as a regular string with a post (the files are small). In flash, flex, mxml, I'm up to no good. I found a ready-made version in mxml, tweaked it so that it looked normal and compiled it into swf. Everything works correctly, but it takes a very long time (for such a small size) to load - about a second, you can safely say "one" =). Both locally and on the site the speed is the same. The size together with three pictures for button states is 44 kilobytes.

Here is a link to a zip with pictures, mxml source and a compiled flash drive: converter.zip

Question: how to make rendering faster / how to write a flash drive differently for the same purpose?
