Any suggestions?
My guess is that the entire hexbin method is fundamentally slow. Among other things, it is looping through all input values in python. In addition, the rendering, using a poly collection, is similar to pcolor, and that is also slow when the number of polygons is large. Profiling a run of hexbin might show whether there are obvious opportunities to speed it up.
