Of course, Xavi, those networks you are drawing are really impressive.
I mean NetworkCanvas::paint executions tells you how many times the canvas has
been redrawn. But you have wired around 120 connections (~25*120=3000) And
the processings you are drawing have the double of ports (the drawEllipse
I don't think there is much we can do about: clipping the drawing area and
drawing just invalidation areas. Even we could migrate to the QGraphicsView
framework which already incorporate this. Maybe in occasions you could be
able to build composites or buses. In fact buses could be a solution also for
the stream efficiecy matter.
