Very slow assembly when adding a real number

[Neliju]

Hi,

When adding a real number with FunctionSpace(mesh, "R", 0) to a mixed function space (see testR.py), the time taken for assembly is almost 30 times larger than if this real number is replaced by FunctionSpace(mesh, "CG", 1) (see testCG.py). It should take less time to increase the matrix size by one instead by #nodes. Anybody have an explanation of this strange behavior?

Thanks.
