I notice that if I use -snes_view,

I see lines like:
  total number of linear solver iterations=20
  total number of function evaluations=5
Just to clarify, the number of "function evaluations" corresponds to the number of Newton (or Newton like) steps, and the total "number of linear solver iterations” is the total number of iterations needed to solve the linear problem at each Newton iteration.  Is that correct?  So in the above, there are 5 steps of Newton and a total of 20 iterations of the linear solver across all 5 Newton steps.
