That sounds really awful, though I don't have a scriptable copy of iPhoto to
confirm it myself. (Smoked my copy of iPhoto 2.0 in the last reinstall and am
too cheap to buy iLife, so am back on v1 now.) Quite possible though - I seem
to recall reading complaints in the past about its GUI bogging down on large
numbers of images, so may be more of the same problem.

Always a good idea to do that if you can. At the moment you're sending about
the most commands you can. You could certainly reduce that a bit; perhaps right
down to just two with a bit of luck: one to get all the photo names, and one to
get all the keyword names for every photo. Not sure how well iPhoto can resolve
more complex queries, but here's the code to try:
p = app('iPhoto')
print zip(p.photos.name(), p.photos.keywords.name())
If that doesn't work, let me know and I'll suggest ways to unroll it a bit.
BTW, the next release of appscript (whenever that is) will include a chapter on
optimising code for efficiency; I just haven't gotten around to finishing it
yet. FWIW, I've temporarily posted some of the notes here:
