Andre mentioned this, but what is the diff for release vs. debug player running this code? In my experience, you can see massive differences between the two.

@David

Yeah, you are right. Count is not needed at all. That was left over from the original code.

You could just len.

Good catch.

Do you really need the ‘count’ variable at all? isn’t it just duplicating ‘len’ = pixels.length ? If so then you could remove one statement from the loop.

Interesting post, Mike.

Well, I believe it would be essential that all these tricks to improve performance get done by the compiler for mobile applications ONLY.

I understand it sounds nuts writting instructions to the compiler to every single bad coding case in order to keep the code appearance and make life easier to developers.

I believe the flash team is doing a great job already by sharing these tricks, tips, tests, etc to the community, this is something we should learn, not to ask the compiler to do it for us.

Hello!
This can be a dumb question. If you’re saying that “Some operations are faster in DebugPlayer than ReleasePlayer”! So how about using an external bebugger? Like Alcon maybe? Just asking :S

“However, I was trying to focus on improvements that I could make to the code today.”

Yeah, that is our daily bread. Workaround the bad compiler. Spending a huge amount of time. I just wanted to point out, that a new compiler would make a difference in future for everybody, not just for cutting edge guys.

@Andre

Yes. I saw Joa’s session at FOTB and Max, as well as met with him a couple of times about his work.

I, and the compiler team, are aware of the improvements that could be made in the compiler. However, I was trying to focus on improvements that I could make to the code today.

@Mike:

“What types of improvements are you seeing?”

Have you tried to test it the way I propose?

If you still don’t get a big performance peak, I will try it tomorrow. Maybe things have change in the last update.
