How to make png encoding much faster? I'm working with large medical images and after a bit of work we can do all the needed processing in under a second (numpy/scipy methods). But then the encoding to png is taking 9-15secs. As a result we have to pre-render all possible configurations and put them on S3 b/c we can't do the processing on demand in a web request.
Is there a way to use multiple threads or GPU to encode pngs? I haven't been able to find anything. The images are 3500x3500px and compress from roughly 50mb to 15mb with maximum compression (so don't say to use lower compression).
