      In a 3-member replica set, with all members living in the same data center. How much slower will w: "majority" be compared to w: "local"?

      During my tests, using YCSB to generate the load, I'm seeing a difference that can vary from 4 times up to 19 times slower depending on the load.

      Please, see the spreadsheet for more details.
