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. |

Since we did packing, this has less value. |
