Validate that a workload that consists of mostly maxtimems second queries achieves effective connection reuse. The notion here is that connection reuse after cancellation should prevent each operation from turning into a new connection establishment.
Perform performance tests against a 3 node replica set with nearest on
- Stream in a steady amount of .5, 1, 2 and 5 second reads (without maxtimems) with read pref nearest, at no more than 10% of overall read capacity for any particular node
- Track how often we are able to kill, then reuse connections
