@drgeo I wonder what would need to be changed, so that these kind of things run in 500 ms

@fantazo Not using @drgeo will help a lot because there is a lot of overheat to build the interactive sketch: each point and line is a morph...
Using directly BitBlt primitive will do the job faster, while non interactive.

@fantazo In the other Profiling this build script will be an opportunity to optimize some part of @drgeo
