Developing for FlashPlayer 10?

I've recently been testing out some of the new features available in FlashPlayer 10, building with FlashDevelop+FlexSDK (FD beta8 makes it easy to build for FP10 - yay) and running swfs in the standalone FP10 debug player.

All was well, but I soon found myself maxing out the cpu with some simple audio operations...

After a coule of tests I found the currently available debug players will execute code a lot slower than non-debug players, even hanging or crashing in some cases.

So, use the FP10 release candidate plugin from adobe labs for faster code execution - but no debugging...
