I’m trying to get rid of the first delay when you run a script or start the app (80 % of the time is waiting on the python Bridge to load itself. The culprit is if you have from Foundation import * in your code. the first time you do that it takes 5-8 seconds. In Imports all of Cocoa and that takes a while. Now you need to import the things on your own. So add a from Foundation import NSWhatever, NSWhatelse, ... to the beginning of you script.
