Previous testing showed that bluestore was a better bet, but that predates the enabling of bloom filters and/or inclusion of bloom filters in the rocksdb cache size. A 50/50 split hedges out bets until we have more information. At worst we are misusing half of any addition memory given to the OSD (vs potentially more than that for any config that steers more memory one way or the other). We still spend no memory on data currently. That should probably change.
