      Right now the default number of applier threads is 16, but that does not scale as a machine has a larger number of cores (and therefore a higher ability to parallelize oplog application). We should change the default calculation of this field.

      We should investigate whether the new default is safe across all instance sizes and post the results of that investigation on this ticket for posterity.
