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.
