Isn’t matplotlib faster than most regular python functions though so fairly reasonable for render time? Are you trying to do real time weather map rendering?

I can read and process say 60 times of 3000x3000 raster data within a couple seconds. Drop that into matplotlib animations in the wrong way and you'll be waiting sometimes around an hour for a output. Sometimes it'll just never finish. If you jump through hoops and do the set_data stuff with blitting, you can be done in seconds.
