      Running YCSB against a sharded cluster in our regression framework, we see a 10+ pause in inserts correlated with eviction in aggressive mode. The pause appears to be on the primary of the second shard of a three shard cluster. The test was run using c3.2xlarge instances, using local SSD for data and journal. The journal is on a separate device that the data.

      Here's a plot of some key stats during the pause:
