Hi again,
how is the quadrature order chosen in ffc? What kind of quadrature
rule du you use? For a stiffness matrix with 2D cubic elements the
generated code uses 9 points, but a 4th order Gauss rule on a triangle
is only 6 points and a 6th order rule is 12 points.

I just need to be sure my benchmarks compare the same thing, so I need
the correct number of quadrature points.

(So far the benchmarks have alternated between ffc and sfc being
faster for non-quadrature code).
