I expect pcolor will be slow regardless of the backend. Have you tried pcolormesh? It is a much faster pcolor-workalike, but unfortunately it has a major bug. If I remember correctly, alpha doesn't work right and resizing a window doesn't work right if some data are masked; things that should get erased, don't. I tried to track it down once but got lost in Agg internals. Anyway, try it and see if it is adequate for what you need to do now.
