It shouldn't be a problem to add scripts.
What settings to do you have for Edit>Preference>Environment>Tile cache size? Given your 4GB RAM it should be set to something between 2GB and 3GB. While Gimp is executing the scripts, check if a big swap file is created in your Gimp profile. If so this is likely the problem, Gimp uses that file when it gets short on RAM but that slows it down significantly. There is a balance to be struck between increasing the tile cache (Gimp competes for RAM with other apps) and using the disk cache instead (runs slowly).
