Hello,
I am reposting with easier data to read as my previous posts were confusing.
What is profiled is an user interaction with a DrGeo sketch: the user drags a point, a segment then the whole sketch is recomputed in real time. The sketch in question is the one shown in picture http://squeak.ofset.org/tmp/profile1a.PNG
When interacting with the sketch, artifacts appear in the smaller morphs like the small red rectangles representing points. There is a tiny delay when they are redrawn, however once the interaction ends, the whole sktech is clean without any artifacts.
I still can't have a text form for the profile on iPad, but I have pasted the two images in one, easier to read in one shot. Sorry. So the profile is in the file http://squeak.ofset.org/tmp/profile1iPad.PNG
I also included a profile of the same interaction on a PC, file profile1PC.txt
Looking at the profile, I see in the iPad a lot of time spent in the method #idleProcess. The #eventLoop also counts for a lot. I don't know how to interpret these two results.
Thanks
Hilaire
PS: for those interested, I have a fee scripts to build from scratch a DrGeo image for the iPad, see https://gforge.inria.fr/scm/?group_id=1308 https://gforge.inria.fr/scm/viewvc.php/drgeo2/?root=istoa
