It takes a long time #44

Closed Dabao55 closed 2 years ago

Dabao55 commented 2 years ago

I'm working with a 960 * 960 pixel image with circle_100 tile, it takes me about 20 mins. Is it because of the poor performance of my computer? Can I accelerate it with GPU? Looking forward your reply.

nuno-faria commented 2 years ago

Unfortunately, this is a CPU only implementation, which means it cannot be GPU accelerated. To improve performance, you can try three things:

Increase the PIXEL_SHIFT config, since a smaller PIXEL_SHIFT will require more computations (or maybe even set it to None to be the same size as the tile);
Reduce the number of RESIZING_SCALES;
Increase the POOL_SIZE to match the number of CPU cores.

Hope this helps.
