Batch "inTxn" operations with their corresponding commit oplog entry if the commit is in buffer

    Details

      Description

      On a secondary, writing into oplog and calling _fillWriteVectors runs concurrently, but _fillWriteVectors is the bottleneck for large transactions. It's better to put operations within the same batch with the corresponding commit, so that writing the operations can overlap with the expensive _fillWriteVectors as much as possible.
