If you have different versions of MPL utilizing different techniques, running the MPL.Graph examples in libs/msm/example/mpl_graph could be a good benchmark.  

It's also easy to construct bigger examples if you need them.

I know that Christophe would appreciate finding out how to make the MSM validators run faster!  As John Bytheway pointed out, many of the problems we've run into result from an explosion in memory usage.
