 Because the storage is shared and there is no direct physical replication happening between primary and secondary compute replicas, technically, the throughput on primary replica will not be affected by adding secondary replicas. However, we may throttle continuous aggressively writing workload to allow log apply on secondary replicas and page servers to catch up, and avoid poor read performance on secondary replicas.
