    Description

      Mixed KV test, 4 nodes, 10 buckets x 5M x 2KB, DGM, 10K ops/sec

      No rebalance, no views, no XDCR.

      On average it's about 3-4GB but there are occasional spikes (see attached chart).
      In this particular run memcached was killed by OS.

      There is a minor regression in basic cases with single bucket as well.
