Thanks, that reduced the plotting time by an additional factor two (besides what I got from reusing the basemap instance). The remaining stuff seems hard to do anything about: - filling masked arrays in matplotlib ~15% of the CPU time - writing the png file (write_png) ~15% - drawing (non-reusable) polygon collections (draw_poly_collection) ~15% - drawing line collections (draw_line_collection) ~7% ...
