All our experiences at work with nginx/psgi & nginx/fastcgi are poor -
it is very good if any of your queries takes any length of time and/or
the fastcgi/psgi requests are requested a lot relative to the static
content served by nginx then there are quite significant
error/performance issues.... In our case the only static files are
mainly images.. The rest of the content is dynamic - whether it is
server cached pages or real dynamic content...
We have a load balancing proxy in-front of our apaches so we can fork
content elsewhere that is to be served fast! We don't because Apache
itself is fast enough! Admittedly we have taken a lot of care to reduce
the overall number of requests to a minimum (page, 1 CSS, 1 JS + a
handful of images per page)
The hacks we would have to do in PSGI/FastCGI to get these features
would probably be negated by the move away from Apache....
Apache is fast enough if you use it properly!!

Speaking as someone would like to migrate to Nginx, at some point, the
big advantage of Nginx really has nothing to do with mod_perl. It has
to do with Apache. The way Apache processes requests is fundamentally
slower than Nginx and, consequently, Nginx scales better.

mod_perl is a much better framework that PSGI, FastCGI IF you make
use of the integration of perl into all the stages of apache (you
can hook into about 15 different stages in the Apache life cycle.
We make of extensive use of the input, output filters, AAA-layers,
clean up, logging, server startup, etc processes then it is one of
the best web frameworks you can use.
We have sites where content is produced by either being static,
mod_perl, php, and java (or proxied back from some ancient CGI
software) all processed by the same mod_perl code in the output
filter to look the same! or different if was using a different site!
If all you are interested in is wrapping CGI scripts in a cached
interpreter for performance then yes you can move to one of these
other frameworks - but then you have already spent lots of time
and effort implementing the features that are virtually free with
apache/mod_perl!
