Has anyone done any benchmarking with dolfin?

I've been comparing some dolfin output to some problems I've  
previously done using COMSOL and I have to tell you I'm not crazy  
about the results.  In particular, I'm interested in linear Stokes  
flow problems around objects that arise out of homogenization and I  
find that when I compute the domain averages of the variables  
( pressure, velocity ), as one does in such problems, the convergence  
to a fixed value as the mesh is refined isn't so good.  I've tried  
both iterative and direct solvers too.
