Reproduced on version r3.6.0-rc4-41-ge608b8b349. On a two-shard environment, I generated a 100% query workload via the load.java attached (which is a modified version of load.java from Configurations tested: Performance of A and C is comparable, whereas B shows 73% the query throughput of A. For the test I used four AWS EC2 m4.4xlarge. One machine for the traffic generator, one for mongos and 1-member config server, and one machine for each shard (1-member replica set). Attached logs and diagnostic data for the three configurations. |
