"TCP offload/chimney settings?" It's always that. Don't know why it even still exists.

I have two existing servers, X and Y. X will be replaced by a new server, Z. Then Y will be replaced by X, and Y decommissioned. These are rather simple file servers. When we brought Z online, we copied data from X to Z via Smart Sync and got fantastic transfer speeds. When we went to copy from Y to X, however, speeds are horrible. What should take several hours is taking days. We then tested communications between Y and Z and speeds are great again. All servers are on the same switch and reside in the same rack. Why would 2 servers communicate so slowly? X to Z = fast Y to X = slow Y to Z = Fast Results are the same whether we "push" or "pull" data.
