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.
