Yes, I'm aware of Box2D integration and I'm very excited about it.
I can't wait to see the possibilities.
But, I'm not sure how much performance boost it will give us.
I've stumbled on an article tonight about algorithm optimizations.
It's kind of a case study.
*Spots* finds the wifi hotspots nearby showing on a map and should react user's
pinch&zoom act with a 60fps speed.

Nikolai managed to achieve a whopping 200x performance increase by optimization.
I tried the unoptimized code in LiveCode.
After seeing the results, I didn't bother to code the binary-search.
Here it is:
----------------- Cocoa & C++ --- LiveCode
iPod Touch--- 194ms ----------- ~2600ms
Mac Pro-------- 4ms ------------- ~ 210ms
These are both unoptimized algorithms
but even if I'd use the binary-search in LiveCode,
I wonder that I could achieve 0.883ms on my iPod Touch or 0.016ms on my
brand-new desktop.
So, an app like *Spots* can never be realized in LiveCode. Achieving a speed
like 60fps seems impossible.
Isn't this kinda frustrating?
I can hear some of you saying:
"Well, get over it pal, LiveCode is a RAD tool.
this is the price you have to pay in exchange of ease-of-use."
Are these features really contradicting?
Can't a coding platform be blazing-fast yet having an excellent IDE, built on
an event-driven foundation and supporting multiple platforms?
I'm not ungrateful, here. Just questioning…
After all, LiveCode's paying my rent for nearly 2 years now.
Best,
