Direct server connection You can use a direct server connection instead of a server connection channel in order to shortcut the connection between a WebSphere MQ connector and WebSphere MQ. You might gain some performance by doing so, but the downside is that WebSphere MQ needs to be installed on the same host as StreamServer, and WebSphere MQ must be of the same version as the supplied java jar files used by the connector. At the moment, only WebSphere MQ version 7 is supports direct server connection.
