The standalone OOB Server is 10x faster at accepting connections than the inetd started server. If you are making a lot of small connections to a UNIX OOB Server then starting it standalone (without inetd) is preferable. The OOB HTTP server is only available when the OOB Server is running standalone.
However, the inetd solution has one advantage which is that if the server crashes for any reason future connections will still work without you having to restart the server.
