Sending Large Data

Use these QoS fields to optimize the process of sending large data.

Use these QoS fields to optimize the process of sending large data.

This includes QoS which help to reduce the number of copies needed and manage fragmentation.

See Sending Large Data, in the Core Libraries User's Manual, for more information.

Basic Settings
