profiling drawing

[Robert Roebling]

  Hi all,

I just read this "bug" report about slow
painting in wxGTK 2.8.X compared to 2.6.X.

https://sourceforge.net/tracker/?func=detail&atid=109863&aid=1786972&group_id=9863

I don't think that anything relevant in 
the drawing code has changed at all since
then and assuming the OP did not hallucinate
or use different configurations the problem
could well be in the mouse scrolling code
(which did change). Now the question is, what
are people using to profile (drawing) code
with the apparent problems of different hardware,
different WMs, dependance on memory, and things
like caching and what not? A quick search revealed
Valgrind and GProf. Does anyone have experience
with these or other tools *for profiling graphics
output*.
