Hi, I would like to point your attention that it's not a good practice to measure latency and throughput in one test.
It should be 2 different tests with different load commands for DBs
Throughput:
In the throughput test, the system can be overloaded, so latency can grow to infinity. You can see it in 3 x i3.xlarge Mongo tests and how P95 Write latency decreases on different environment at scale-up ( 3 x i3.2xlarge)
The second problem is not enough load. In the current tests, max throughput may not be achieved.
The marker for this is the same - decreasing P95 Write latency in Mongo tests.
Latency:
For latency tests, System should not be overloaded(especially the CPU) and work in normal conditions.
Also, the current tests compare the latencies of 2 databases while different load (throughput) is running there
