Thanks to all for the useful advices! I've done a profiling with a simple django application and it showed that the bottleneck is flup. My django application often serves big HTML/XML pages (about 1-2 Mb) - in such cases the overhead of FastCGI implemented in python becomes tangible. That's why django application deployed under Apache+FastCGI ot Lighttpd+FastCGI runs slower than under Django development server or Apache+mod_python.
I found the python-fastcgi implementation, which is a wrapper around the Open Market FastCGI C Library/SDK (http://cheeseshop.python.org/ pypi/python-fastcgi). Then i changed django.core.servers.fastcgi to use WSGI server not from flup, but from python-fastcgi. And the performance imporved greatly! It became even faster then Apache +mod_python. Django deployment documentation claims the need of flup as the FastCGI library. Are there any flup features that Django relies on? Is there any experience of deploying Django application with FastCGI but without flup?
