Performance for YCSB 50/50 tests with w:majority has regressed compared to 3.0.7. This happens to both wiredTiger and MMAPv1 storage engine. We should investigate and fix this. |

This will be "fixed" by new functionality which will allow the users to specify the journalled-ness of w: majority writes. See SPEC-444. |
