Description:

Which high performance transports does TAO support?

Resolution:

TAO provides two transports which can potentially offer better performance then IIOP. These are:

UIOP: GIOP over local IPC (UNIX domain sockets)
UIOP for communications on a single node typically offers 30-50% better performance across the board over IIOP

SHMIOP: GIOP over shared memory
SHMIOP on the other hand is typically faster for invocations with large payloads but with relatively small amounts of connections in the system (in our experience).

In a UNIX environment the TAO UIOP plugin outperforms the SHMIOP implementation.
