Yes

My conclusion that the view was functioning quickly was from a print
time.time() test I did. According to that it took .2 secs from start
to the point right before the view called render_to_response().
Again, this was on my dev site which doesn't have as much data.

I took that out of the loop and it made a big difference. Makes total
sense too, I was doing a lot of extra work there but didn't realize
it. The time difference was dramatic. I timed it using basic
sys.stderr.write() and .flush() with apache2/mod_python.
creating classes inside the loop, calling newforms.form_for_model() 19
times:
for p in ... 1175239555.13
done with for p in ... 1175239601.91
47 Seconds?!
only creating the class once:
for p in ... 1175239882.93
done with for p in ... 1175239886.7
3 Seconds!
So I think that was it.
This is on django-svn 4455, a bit outdated. I tried updating a few
days ago but some non-backwards compat code bit me and had to back off
for a bit.
Thanks Gary and Everyone!
