This is the performance counterpart to SERVER-105619. We have seen issues arise in replica sets that move to an upgraded binary version but stay on the lower FCV for a prolonged duration (example ~~SERVER-103697~~).

We should add performance testing.

is related to

SERVER-103697 [v8.0] binVersion 8.0, FCV 7.0 clusters may experience replication lag due to internalInsertMaxBatchSize == 500 default setting

Closed

SERVER-105619 Add more testing for clusters where every node is on the upgraded binary but downgraded FCV
