The newest version of FIAT is much faster than the old.  FIAT-L (on the 
Web site) implements this new architecture, but the full version of 
FIAT that supports other elements (such as Brezzi-Douglas-Marini) will 
be released soon.  The timings below are for instantiating (this 
involves at least inverting a large vandermonde-type matrix and in the 
case of BDM elements, a possibly large SVD) elements and for tabulating 
them at a set of quadrature points (the number of points is appropriate 
for the degree of the polynomials.

Next on the to-do list is generalizing the generation of dof maps in 
FFC so as to leverage these higher order Lagrange elements.
