Transports enable the exchange of objects and data between different server processes in your configuration.
If you are using eXtremeMemory, a new transport that is called eXtremeIO is used. With eXtremeMemory, cache entries are stored in native memory. Native memory does not go through garbage collection, leading to more constant performance and predicable response times. Objects are serialized into bytes on the container server. For more information, see Configuring IBM eXtremeIO (XIO).
