I've just read over the git log and can't see anything which jumps out at me. Perhaps some potential changes in performance on polygon operations, but those aren't happening during benchmarking anyway, the "NoHoles" polygons (are / should be) cached. I'd be fascinated to see results of a git bisect between the pcb-20091103 tag and git HEAD to see where the performance dropped. pidpeltier looks like the board with the most dramatic difference between the versions. If you fancied sending me any of the boards off-list, I'll have a play and see if I can make PCB+GL faster with them ;) -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
