Why are the default # of processes and threads set to 1 and 15, respectively? about modwsgi HOT 4 CLOSED

If nothing else, the documentation on this page could suggest some reasonable 
defaults for a typical Python web application:

Please note that the mailing list is a better forum for discussion.

Because web applications are normally I/O bound, the GIL is not the big problem 
people think it is and multithreading tends to be more than adequate. 
Multiprocessing only becomes more important when you are talking about CPU 
bound activities.

More important in web applications is usually memory usage and using single 
threading and many processes will use a lot lot more memory. This will often 
exhaust a users system memory long before they reach any performance issue due 
to the use of threading.

So overall the safer option for the typical user is a single process with 
multiple threads.

As to reasonable defaults, that is an impossible question to answer as it 
depends on your specific web application. There is no one right way.

I would suggest you go watch my talks:

OK, well thanks for the reply. I agree that "reasonable defaults" is 
subjective, and I will check out the talks. Thanks again.

Closing out documentation issues. Will pick up another time on github side when 
get enough momentum to work on documentation again.
