If you eschew creating a new display for each image, your script should run significantly faster. Creating a new image is quite quick, however, creating a new display takes quite a bit of time.

Another option -- if you desire to see the images as they are processed -- is to use the PDB function 'gimp-displays-reconnect' to reconnect a single display to each image as it is processed. This will obviate having to create a new display and avoid regenerating the GTK menus (which makes creating a new display take so long). Note that you will still need to delete the old image (to avoid a memory leak) after the new connection is made.
