Network is now outpacing single core performance.

The same 25 Gbps claimed by the article can be achieved with a single-threaded ZeroMQ socket. That thread will be CPU bound. To break 25 Gbps, multiple I/O threads need to be engaged.

There are already greater than 100 Gbps network links while single-core speed has stagnated for many years. Multi-threaded or multi-streamed (like in the article) solutions are needed to saturate modern network links.

Yep, you can't do fast anything in software without parallelism in the modern world, as single thread performance improvements have stalled even harder than networking speed improvements. I guess my observation might be a symptom of parts of the software world staying behind at the single core performance level and only specialized applications bothering to do the major sw surgery that 10x or 100x parallellism requires.
