As you get older, you get smarter…

The tagline is “Erfolg ist eine Frage des Timings”, which roughly translates to “Success is a question of timing”.

The context is that late night political negotiations go all night, and with a nappy on you don’t need to take a break from your wheeler dealing.

and for completeness, 64b packets - the smallest possible on an ethernet network, failing at atound 13.5Mpps, which is 36% line rate.

looking at the block diagram, you can see that there is this passive component that sits between all the ports and the CPU, and so the max bandwidth we can expect between any two ports is in fact 25G full duplex.
