Well, *any* language will work with Nginx, as long as it has an 
HTTP/FastCGI/SCGI server implementation.

As for languages embedded inside Nginx, the only choices at the moment 
are Python and Perl.

The memory usage usually depends on the package you use.
The python interpreter in mod_wsgi takes about 3616 KB in the master 
process and 1908 KB for each worker.

io seems interesting, I did not knew it.

Lua seems the best choice, however it does not have all the packages 
available for Python and Perl.


I'm very interested in developing a module for lua (or io), mostly for 
testing the best possible integration with the Nginx event module.

For mod_wsgi I have implemented the ngx.poll extension:
http://hg.mperillo.ath.cx/nginx/mod_wsgi/file/tip/examples/nginx-postgres-async.py

but it's not very usable yet.


For really scalable applications you can also consider Erlang; 
unfortunayely its syntax is not good, but many use it since there are no 
better choices (Haskell is interesting too, but it is not as mature as 
Erlang for network applications - and this is very unfortunate)

You can test it with Nginx mod_perl and mod_wsgi.
However if the application is IO bound, then the performance are not the 
best.
