Slow page in admin

I'm new to Django and I would like to apologize if it's been asked before.

I have two models Region and Zip. In the admin system, Zip is an inline model in Region

Whenever i want to add a Region it shows directly 25 listboxes with zips. This however takes a long time to load the page and results in an internal error.
There are 2,774 records in the zip table.
I suspect the cause of this error is that for each list, Django connects to the database to fetch those records.

Is there a way to solve this?

Thanks in advance
