However, this should normally be a pretty simple task to measure. A little program which establishes a socket, SYSV or POSIX message queue, send X bytes and measure the time it takes. I've done some tests between SYSV and POSIX message queues. My experience is that the POSIX implementation is much more efficient. kind regards, David Sommerseth
