    Description

      With new XDCR protocol we need to tune the default replication streams. Currently the default is 32 streams.

      • - - - - - - - - - -

      Key parameters: CPU utilization (both source and destination) and XDCR throughput.

      Possible range for number of replicators: 1 - 32.

      "Binary search" for optimal xdcrMaxConcurrentReps (minimum CPU usage while not making a trade-off with throughput).

      Target build: 2.2.0-809.
