Performance issue with Flex

[magnus]

I ran into a fatal speed/performance issue when trying out this great
engine - the frame rate dropped to about 2-3 fps when compiling with
Flex Builder...

So, when using Flex Builder remember to disable debugging. Go to
'ActionScript Compiler' settings and add '-debug=false' to Additional
compiler arguments.

This will disable all debugging information being compiled into
the .swf. Unfortunately this will also result in no console-traces and
no stack-traces, but also smaller file size and great performance :-)
