Disable TCP Delayed ACK
In particular, delayed Delayed ACK, which is a basic property of TCP in Windows, helps to optimize transmission by waiting for a certain amount of time when sending an ACK response from the receiving end, and then collecting and processing it at a time. However, this property has a bad effect on latency and should be disabled. The following command disables this option on the network interface, which can be controlled on a per-resource basis in bsrbandwidth but has a bad effect on delay time, so it should be disabled manually. When bsr is first installed, this is automatically performed by a script during the installation process, but if the LAN card is replaced later, this task must be performed manually again.
The following is a command to disable Delayed Ack for a network interface. Specify the interface by IP address or guid.

This command is for Windows only. It sets TCP option values in the Windows registry and applies the contents to the network interface. You can check the registry contents in the path below to see if this option has been applied properly.
