If in fact I am….how do I avoid this?  I have been playing with alternatives for a week and I'm starting to lose it…lol

If you're using model choice fields, it's very likely you are making an SQL query for each form set. It should be pretty obvious in the log with debug turned on.

Steven, are you using ModelFormSet?  If so, Is it the initial query
that's slow?  The form rendering?  Or is it the POST back to the server
that's slow?  You can use django-debug-toolbar[1] to profile your page
and get these metrics.

Once you figure out what part is slowest, then you can optimize.

Hope this helps!
