Essentially, there are currently two algorithms in the program that do not scale linearly with the number of degrees of freedom: renumbering of degrees -of freedom (which is ${\val O}(N \log N)$, and the linear solver (which is -{\val O}(N^{4/3})$).

As for the first, while reordering degrees of freedom may not scale linearly, it is an indispensible part of the overall algorithm as it greatly improves the quality of the sparse ILU, easily making up for the time spent on computing the renumbering; graphs and timings to -- 2.39.5
