Maintaining an open connection

[Zuri <zi...@hotmail.com>]

Working on an authentication module that will support a "very" large number
of incoming requests, on the order of millions per day. The module performs
authentication processing and needs to talk to a server AuthProxy (not on
the same machine) that in turn, relays the requests to a number of other
systems. One of the performance optimizations we're considering is to
establish and maintain a single connection to the AuthProxy and  use
throughout the life of the module/process instead of continuously
establishing and tearing down TCP connections. Any advices on this? Any
references or other modules that we can look at for assistance?

Thanks.

Thanks for the pointer. Has anybody compiled stats as to what kind of
savings this (maintaining an open connection vs. establishing and
tearing-down every time) entails?

mod_authn_dbi keeps connections across requests:
http://open.cyanworlds.com/mod_authn_dbi/

It uses apr_relist(part of apr-util) to keep its DBI connections alive, but
apr_reslit could easily be used for normal sockets.
