Description

Disables nagling. Nagling is a TCP feature that combines several small packets into a single, larger packet for more efficient transmission.

By default, Message Queuing (also known as MSMQ) enables nagling on the TCP sockets it uses. This improves overall performance, but it might briefly delay transmission of smaller packets. If the delay is undesirable or unacceptable, then you can add this entry to the registry to disable nagling.

Value Meaning

0

Nagling is enabled.

1

Nagling is disabled.

This entry does not exist in the registry by default. You can add it by using the registry editor Regedit.exe.
