Definitely take that specific dynamic page and profile it - see what's
happening and why its slow. That's clearly your first bottleneck to
work on from the data you've provided.

There's a wiki page on that very process here:
http://code.djangoproject.com/wiki/ProfilingDjango and there's
additionally some information you can get when you enable DEBUG to see
how long the SQL queries are taking for that dynamic page. There's a
nice snippet to help there at
http://www.djangosnippets.org/snippets/93/
