Hi,

with 0.9.7 version a major slowdown on dolfin is noticed also.
This time I used  the advection-diffusion demo.

I've tested with the following settings:

Summary of timings______|  Average time  Total time  Reps
------------------------------------------------------------
PETScLU 0.9.7_________| 1.31        1.31     1
PETScLU 0.9.2_________| 0.81        0.81     1
uBLAS 0.9.7___________| 2.65        2.65     1
uBLAS 0.9.2___________| 0.96        0.96     1
uBLAS Factorized 0.9.7_|  0.68        0.68     1
uBLAS Factorized 0.9.2_|  0.39        0.39     1

Any ideas?
