Do also heed my comment:
"""Do note though that any gain in performance over mod_python will be
immediately swallowed up as soon as you load up one of the large
Python web frameworks such as Django or TurboGears. This will
especially be the case where a database backend is being used and is
because most of the overhead will then derive from the Python web
framework and any bottlenecks in accessing the database. Any overhead
from mod_wsgi will be a very small component of the total and so any
gain in that area will hardly be noticed."""
