+- The ``named`` daemon uses load-balanced sockets to increase performance by
+  distributing the incoming queries among multiple threads.  Currently, the only
+  operating systems that support load-balanced sockets are Linux and FreeBSD 12,
+  thus both UDP and TCP performance is limited to a single-thread on systems
+  without load-balancing socket support. [GL #2137]
