Just increase the rate until you lose the keyboard. What is your idea of a "modern"

Is there a way to direct specific interrupt activity to a single processor, or to tune the
behaviours in any way? It seems absurd that there
is no networking benefit to adding another
processor two years into the project.


Unless you are ready to write support for interrupt affinity, cleanup the APIC code to use logical topology and do the necessary cleanups to the PCI interrupt routing code, these things take time.

The amount of hands at DragonFly's kernel code are limited.
