Does DFS Replication perform bandwidth sensing?
No. DFS Replication does not perform bandwidth sensing. You can configure DFS Replication to use a limited amount of bandwidth on a per-connection basis (bandwidth throttling). However, DFS Replication does not further reduce bandwidth utilization if the network interface becomes saturated, and DFS Replication can saturate the link for short periods. Bandwidth throttling with DFS Replication is not completely accurate because DFS Replication throttles bandwidth by throttling RPC calls. As a result, various buffers in lower levels of the network stack (including RPC) may interfere, causing bursts of network traffic.
