I didn't check that specific version of open-mpi. I cannot guarantee to find much time to look into this problem but if you could provide a simple test case...
I used http://lists.boost.org/boost-users/att-83807/test.cpp which showed that boost::mpi was at least 10x slower than MPI for sending largeish vectors between two processes on a laptop with openmpi 1.6.5 but the problem didn't seem specific to openmpi. Ilja
