Well, just big WOW!


Only I wonder ... You sure that RB's best time is 25 sec?

When few year ago I did benches of Valentina
I did them in REALbasic project.
I have measure overhead of RB plugin itself.
And I must say - I did not see that RB is slow.
It was TIMES faster of Revolution or Director.

And in my head present number that RB is about 5-10% of C code...

May be something was changed in RB.
May be you use something what I did not use e.g. Classes

On the other hand this is not important now.
You go to ObjC and you have great results now on hands :-)
