speed up results with dg and the new assembly (which now seems to work also for dg)

time for new assembly       4.40532803535  with  uBLAS
time for standard assembly  4.48198795319  with  uBLAS
time for new assembly       3.899477005  with  PETSc
time for standard assembly  4.40028500557  with  PETSc
time for new assembly       4.32548904419  with  Epetra
time for standard assembly  4.36159396172  with  Epetra

Hence, the speed up is very small (except for PETSc)
