I am finding that one possible show stopper is the gegl gaussian blur. Here is a simple example. Open a 16bit, say 12 MP tiff image. Duplicate Layer, and run gegl gaussian blur with x=y=100. On my Macbook Pro with 8G RAM, either I will get vertical lines on the layer (at best) or crash my Mac. Is there a way to speed up gaussian blur or is this a Mac issue and never happens on Linux?
