Re: [Gimp-user] python-fu vs script-fu
It is difficult to estimate. Interstingly perhaps, (as noted by Ofnuts) it can be significantly more, perhaps 2, or even 3 times longer on a first run.

Re: [Gimp-user] python-fu vs script-fu
How much extra time are you seeing with the Python dialog? Here on a Windows 7 machine, I can't be sure I'm seeing any difference, so it must be less than 0.5 seconds.

Re: [Gimp-user] python-fu vs script-fu
Intersting idea, but running Python interactively before launching GIMP does not seem to make a noticeable difference.
