I expect it will have only a moderate effect. The generated code does
currently not use BLAS (although FFC generated BLAS code earlier at
some point, currently broken) and matrix insertion does not use BLAS
afaik. So assembly should be unaffected. Possibly it might have some
effect for the solve step. Will be interesting to hear what you find
out.
