*Network message cache size*

Type: ``int``

Help
====

.. code-block:: none

    Number of messages that are cached for the network. This helps
    prevent unnecessary decryption operations and unnecessary
    relays. This option is similar to the replay protection list,
    but has a different purpose.

Direct dependencies

*(Includes any dependencies from ifs and menus.)*
