Speed up to 4 processors should have at least 40,000 equations for 3D
problems and more for 2D.
At least for iterative solvers. This is probably a good place to start with
direct solvers but you might see benefit with a little less.

Thank you for your reply.
It was a simple problem, but it has more than 1000 degrees of freedom.
Is this not enough to check speedup?

Dear petsc developers.
Hello.
I am trying to solve the structural problem with FEM and test parallel
computing works well.
However, even if I change the number of cores, the total time is calculated
the same.
I have tested on a simple problem using a MUMPS solver using:
mpiexec -n 1
mpiexec -n
