In terms of latency... well... we also could do a lot better there, but as I understand it, even if you do your best to cut away as much software bloat as possible, the latency "floor" seems to be higher than in the old days[0]. And the many layers of abstraction that is the average software stack don't help. Like, I'm doing my best to keep a web-app snappy, but there's only so much you can squeeze out of a browser.
In terms of throughput, absolutely.
