    Description

      Noticed that Rebalance consistently taking longer time in 2.0.2-755 than 2.0.1-170.

      Consider the last or last 2 results from each rebalance job on:
      http://dashboard.hq.couchbase.com/litmus/dashboard/?env=thor

      Also consider the graphs of rebalance jobs attached in http://www.couchbase.com/issues/browse/CBD-914, to note the increase in rebalance times.

      Logs and graphs from reb-out-large-2 attached.
