Dear all, I have been working on how to speed up some raster processing that require long time when performed on large files. I wrote a script that use the multiprocessing python module and it works well if I use PyCharm, reducing more than the half the time necessary to process the image with my 4-cores processor. I can see all my cores max out in the System Monitor and I don't get any kind of error.
The problem comes up if I try to execute the same script as a Processing Toolbox script, it never ends and after long time qgis crashes.. That's a pity because it would be great to have and use it directly inside qgis! Is there a way to fix this problem or another way to perform the same? All the best -- Sergio Vignali
