So, I finished my rebuild, have lots of shiny new processor power and 6 GB of ram ... and GIMP won't use it. It chugs like the dickens while my resource monitor says I'm only using about 50% of my ram and 25% of my processor power.

Do any of the gimp experts around here know if/how I can tell it to hog all the resources it wants? I checked the preferences and it is set to use all 4 processors; none of the other settings look relevant.

The good news is that at least I can use my tablet now.
