It seems quite slow. I am using Python 2.6.4 on Linux, slow processor (~2GHz). I out-commented the testOpacityFrequency and _compare defs in the test/pil.py. Now I added about 10000 points and it is calculating for half an hour already. With 1000 points it tool 5 minutes.

Is that normal performance or did I do something wrong?

edit: after 36 minutes it threw "AttributeError: 'LoadTest' object has no attribute '_compare'", oops that was my fault. Trying again with less points.

edit2: It is swapping... I have 2GB RAM. Using an 8192x8192 image and 20 points. :-(

Ok, so with a 2048x2048 image it works alright. Still quite slow though.

But I am rather sure it is tailored for click heatmapping.

1000 points on 2048²: 4 minutes 10000 points on 2048²: 34 minutes

Sadly that is too slow to be of use for me. Or maybe I simply did not use it right.
