over them total.
Do you hit CPU limits at that point?

very usable at that point, ifconfig aside).
The interfaces are a linked list, plus there's a separate kernel dive
for each interface. The list (as opposed to individual interfaces) is
i don't care how fast ifconfig displays them, just for how fast things
