[Boost-users] Boost graph parallel issue

I want to utilize boost MPI to increase performance of graph code. When I run standard examples in libs/graph_parallel/examples/, bfs does not give better performance with more than 1 process taken in mpirun (using openmpi 1.8.3). The timing is as follows:

No of Processes          Time (ms)

1                                  40.80 
2                                  82.19
4                                  92.67
8                                  76.86
16                                91.61

Any suggestions to improve the performance with processes as graph parallel should use more ranks for better performance.
