I’m somewhat reluctant to overclock the board, as it is the only one I have currently ;).
Regarding the affinity settings, I used mainly the interrupt distribution shown in /proc/interrupts for checking if I get any effects. Since I cannot split the interrupt handling for the interfaces or for rx/tx , I can only shift all of the network handling to cpu1, which the github commit you mentioned above does. I tried it during my test, but setting the smp_affinity to 1, 2 or 3 did not make a real difference.
