Dear Seyed Ali,
no idea, but possible reasons :
1. Do you compute on the same mesh?
2. do you compile in release mode or debug mode?
Release is faster.
3. Possibly you can optimize deal.Il with respect to the CPU etc.
On my desktop computer at work, deal.II is 2 - 4 times slower than
on my laptop for instance.

Dear Thomas,
I was wondering, why my computation is rather slow compared to your
results within your paper. For instance regarding the shear test you
mention that for global refinement the total time amounts to 5036 s.
In my case each step takes around 200 s which would result in a total
time of 30200 s (for 151 steps). What could be the reason?
Attached you find the terminal output from your approach.
