This is ~truly~ in a class of its own. He he, fail :-) I remember doing some design decisions that I knew were bad for smartphone performance, but this was a long time ago. I wonder what the main problem is these days. Any chance to get profiler output? If it's mainly stuck inside python code then there's probably not much that can be done with reasonable effort. If it's mainly inside C code then maybe something can be done. If you are lucky it's just the silly use of floating inside draw_dab() that your CPU doesn't like. Or maybe you can tune the TILE_SIZE constant to keep the pixels inside the CPU cache. If you're unlucky, the 16bpc pixel format is just too much for the n900. PS: I think Luovatone is doing the n900 builds. I'm not sure if he's reading this list, and I don't think I got his email. If you want to help, maybe you should try to ask him.
