There is a lot of load imbalance in VecMAXPY also. The partitioning could
be bad and if not its the machine.

Something is odd about your configuration. Just consider the time for
VecMAXPY which is an embarrassingly parallel operation. On 1000 MPI processes
it produces

Dear PETSc team,
I am solving a linear transient dynamic problem, based on a discretization
with finite elements. To do that, I am using FGMRES with GAMG as a
preconditioner. I consider here 10 time steps.
The problem has round to 118e6 dof and I am running on 1000, 1500 and 2000
procs. So I have
