Does anyone know of a good way to enable TCP_NODELAY on sockets when you don't have access to the source for that application? I can't find any kernel settings to make it permanent, or commands to change it after the fact.

I've been able to disable delayed acks using `quickack 1` in the routing table, but it seems particularly hard to enable TCP_NODELAY from outside the application.

I've been having exactly the problem described here lately, when communicating between an application I own and a closed source application it interacts with.
