I have 16 GB of RAM and the recommendation is half.  My cache is 8 GB which is the recommendation.   I don't see a way to select the drive which Gimps uses to swap, is there a way?  One might assume the default is the OS drive??
Many times when I am using the color curve tool Gimp seems to call up all of my external drives. I know because they pop up on the screen when I make an adjustment, likely because there may not be immediate access to the drives?
I'll try bumping the cache to 3/4 of the RAM which is another recommendation and see if I notice any difference.
