In fact,
As normal web server, the maths would also be
max_clients = worker_processes * worker_connections / 2
since every browser opens 2 connections by default,

I would say "and nginx uses the fds (file descriptors) from the same pool to connect to the upstream backen" (wiki quote). But that should be 2, not 4: I agree with you on this. If any of the gurus out there could shed light on this, I'm sure a lot of us would appreciate.

In the wiki (http://wiki.nginx.org/EventsModule#worker_connections), it said:
----------------- The worker_connections and worker_proceses from the main section allows you to calculate maxclients value:
max_clients = worker_processes * worker_connections
In a reverse proxy situation, max_clients becomes
max_clients = worker_processes * worker_connections/4
Since a browser opens 2 connections by default to a serve...
-----------------
Why only in reverse proxy mode, the max clients is it divided by 4, but not divided by 2 as normal web server?
