GIMP 2.8 is not ported to GEGL.

If I try this on git master (which IS ported to GEGL), it takes much
less than a second on my linux machine, and is even faster on
my Mac, even though there is zero threading and only one processor
used.

I don't currently have 2.8 installed on this Mac, but it can hardly
be slower, unless the threading got broken in GLib, try to set
#processors to 1 in prefs and try again.

Also, what build are you using? Native or X11?
