</div>
<div class="">In terms of code performance, sometimes people would ask for info about total non-linear iteration numbers, total linear iteration numbers, etc. I suppose all these could be found in the log summary. For the attached log summary, can I say?</div>
<div class=""> total non-linear iteration number = 573</div>
<div class=""> total linear iteration number = 2321</div>

<div>Usually SNESSolve corresponds to the number of nonlinear iterations in the summary. It seems that you are solving some linear systems with GMRES. And there are 573 linear solves with 2321 GMRES iterations in total.</div>
