The NIC is able to handle wire speed without additional latency, lowering the work it does does not free things up for other traffic realistically.
Maybe this part is the key. Are you saying that whatever handles the processing in the adapter is so fast that it's basically 0 ms? So that the embedded processor in the NIC, even when handling 5 separate applications' worth of information workload, say a large file transfer, a bunch of web pages, IMs, websocket data, etc, will always be 0 ms and that there's no subprocessing at all?
In my mind latency is a byproduct of a few different components, the network beyond the laptop, but internally on the laptop, the time it takes for the CPU to hand a request off to the NIC, and then the NIC to translate that request into appropriate formats and packets, and then the time for the NIC to intermingle that w/ the streaming it's already doing to the router. So by reducing the work in any one of those steps you're getting closer, even if only theoretically, to 0 ms.
