Re: Calculating the max. clients by worker_connections

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.
