Re: [Gimp-developer] gimp 2.8 prohibitively slow

[Aaron Paden <aaronbpaden gmail com>]

It's definitely on the low end, but I'm positive that gimp can do 
better! Of all the graphics programs I've tried on this computer, gimp 
2.8 performs the worst. Even krita is a little better, which I thought 
was surprising. It's able to at least load my largest image (8960x9088, 
7 MB) after awhile without halting and crippling my DE, though it takes 
about 6 seconds to register from pen to paper.

I'm not quite sure how the MyPaint guys do it. I think it might involve 
virgin sacrifice.
