Well, easiest to explain is user apps that use tcp or udp sockets to
communicate. If they are on the same host, then huge gains can be
achieved by using the loopback adapter (especially TCP comms).
Thanks, but again, is this related to systemd-network in any way? My
question is whether letting systemd-network manage the loopback
interface is useful or not, not what the loopback interface is used for
in general.
As far as I understand, systemd itself brings up the loopback interface
on its own during the early boot stage, and systemd-network(d) is
launched much later. But is writing something like this in
/etc/systemd/network/foo.conf ever useful?
$ cat /etc/systemd/network/foo.conf
