For example, I try to avoid doing as much work as possible during the
double loop over DOFs which is the inner most loop. Sometimes
pre-calculating things in the outer loop really speeds-up the
calculation. This also depends on the polynomials you are using for
interpolation. If you are using high-order polynomials, I think this is
where you will reap the benefits of Matrix free significantly.
This is extensively discussed in step-22, as a point of reference.
