In our projects (from examples to prototypes), we aim to have no more than 300 000 polygons per stage. For example, If an imported object has 10 000 polygons, we keep no more than 30 of its copies in a stage. The same applies to strokes (something you can draw), the longest, most complex stroke (where it stops drawing automatically) will be around 10 000 polygons—so it’s better to have no more than 30 of them per stage.
