But the CPU is not the limiting factor.
Back to the funnel analogy: you have a big bottle and you are using a small
funnel. That will not work well. If you use a bigger funnel with the same
bottle (the bigger funnel must fit the bottle), than you can handle more
liquid.
If the funnel is too big for the bottle, then you are spilling out and this
is the scenario that you are referring to.

Fair, but when have you found CPU to be the limiting
factor in Kamailio's
throughput? Kamailio's workload isn't really computational / CPU-bound.
It's closer to something like Node; it's an I/O multiplexer.

That could be one scenario. But when I’ve seen there being more than
enough CPU it
has been there’s a more for 2MB worth of traffic and the OS
is making an issue that is easily solved by letting the system handle more
traffic.
It’s a bottleneck before kamailio.
The analogy would be a funnel. At some point, when you’re pouring a lot
of liquid,
you need to use a wider funnel. Ain’t nothing you do after the
funnel will matter. The funnel is the problem.
