No clue. How have you determined that that line of code is taking 20 seconds
to run?

Since you say you can recreate with the dev server on this machine, I would
probably tackle this with pdb by putting a breakpoint before that code,
stepping into the execution of CompanyFormset(request.POST, request.FILES),
and then stepping through the code to narrow down where the big delay is.
