I'm using it in Daemon mode:

WSGIProcessGroup wsgi
and apache is with prefork:
httpd -V

I changed the module for the most recent release and for my first
configuration (10process and 40 threads) It haven't changed much.
But after reviewing your post
http://blog.dscpl.com.au/2012/10/why-are-you-using-embedded-mode-of.html I
tested with 40 process and 1 thread and the average request response time
have drop by at least 50%.
I will repeat the tests with the old module to ensure that it was this
upgrade that reduced the average response time.
Thanks again.
