[openbeos] profiling

Hi all,

could someone point me to some good guide(s) on profiling under BeOS? I 
have now tried several things on my list of accelerating Painter, none 
of them gave great improvement. I would like to know where exactly the 
bottlenecks are, but I have never really done much of this "real" 
profiling stuff before.
Painter is now implementing all drawing_modes and the pattern drawing 
correctly, but it is much slower compared to BView. For random or 
horizontal/vertical lines of 1 pixel width in B_OP_COPY / B_SOLID_HIGH 
mode: 10x without anti-aliasing, 39x with anti-aliasing. I'll keep at 
it...

Best regards,
-Stephan
