currently the GEGL operations in GIMP are very slow. I have done some
basic profiling yesterday and it appears that the main problem is the
conversion from floating point to 8bit. Here is where the most time is
being spent.

Changing this in GIMP is not feasible. What needs to be done is to
implement shortcuts for the conversions that GIMP actually uses.
Eventually he gimp-8bit extension should provide shortcuts for both
gamma-corrected and linear 8bit - double

8bit - float conversions, of course.

Hello,
I can give it a try. If I understand it correctly,
gimp-8bit.c only implements u8-float conversions, which
seem to be picked up by BABL correctly, so the problem lies
in the float-u8 conversions that are computed by
ReferenceFish. Is that correct?
I just had a short look into
