There are a number of MPI benchmark programs out there, including NetPipe, OSU, etc. All of them do some form of message exchange and report latency and bandwidth as a function of message size.
You'd have to look into them to see if they match your specific communication pattern. A quick web search for MPI benchmark will yield a lot of hits.
