First, discretizations are very important for AMG solver. All optimal
solvers really. I've never looked at serendipity elements. It might be a
good idea to try Q2 as well.

Dear PETSc team,
I have run a simple weak scalability test based on canonical 3D elasticity
problem : a cube, meshed with 8 nodes hexaedra, clamped on one of its face and
submited to a pressure load on the opposite face.
I am using the FGMRES ksp with GAMG as preconditioner. I have set the
