What would you recommend as a "real-world" dbus benchmark to try out?

The dbus-ping-pong one isn't real-world, but it is fast, and you can run
it in the kdbus git tree if you want to try it out.  There are also
other benchmark tests in the systemd repo that show how fast it takes to
send/receive data of different sizes across the kdbus boundry through
the systemd library wrappers.  Try those out on different machines if
you are curious as to the speeds involved.
