It's a board that I codesigned a long time ago (the White Rabbit Switch v3.0) and crudely converted from Altium to Kicad as a performance test. It's a very pathological test case, including split power planes converted to many polygons with extremely complex outlines and lots of tracks not centered on pads/vias (which Altium frequently does). It takes approx 3 mins to refill all zones on my machine ( i7-4700MQ, 16 GB RAM). For comparison, two rather complex designs done from scratch in Kicad take much less time to refill. - A64-Olinuxino : 17 s - cible_ccd (JP's project) : 21 s Heikki, I'm interested in your parallel zone filling algorithm. Do you have it in your Github?
