The socket options for the listening socket in CouchDB can now be set within the CouchDB configuration file. The setting should be added to the [httpd] section of the file using the option name socket_options. The specification is as a list of tuples. For example:

[httpd]
socket_options = [{recbuf, 262144}, {sndbuf, 262144}, {nodelay, true}]

The options supported are a subset of full options supported by the TCP/IP stack. A list of the supported options are provided in the Erlang inet documentation.
