[aspect-devel] Aspect Timer

[Eric Heien]

I tracked this issue down to the following line (core.cc:312):

    DoFTools::count_dofs_per_block (dof_handler, system_dofs_per_block,
                                    system_sub_blocks);

This seems to take a long time after each checkpoint.  Any ideas?
