We observed a significant regression in the ycsb_100read benchmark (see ycsb-mongodb/workloads/workloadc and dsi/configurations/test_control/test_control.ycsb.yml). Just to give a perspective, the throughput dropped from 55k for 4.2.0, to 36k for 4.3.0, to 19k for 4.4.0 when the ycsb_100read benchmark is run against a single-node MongoDB replica set.
