This test currently doesn't account for actual network conditions. It uses the expected (i.e. target) number of queries per second to calculate the expected number of queries per second. This has caused the actual number of sampled queries to sometimes be very off from the expected as can be seen in BF-26996 and BF-27198. Therefore, the test should use actualNum{Find,Delete,Agg}PerSec instead of the targetNum{Find,Delete,Agg}PerSec to calculate expected{Find,Delete,Agg}Count.
