    Description

      Replicated inserts are currently processed on secondaries as an update (w/upsert:true), not an insert as an extra, but unnecessary, guarantee for idempotency. This is more expensive than the original insert on the primary so it cause differences in performance on secondary, like increased resource allocation (cpu) and/or latency (replication lag).
