so, after reading the article, yeah, think he explained it a little bad. basically what he's saying in a single node thread node's parallel model doesn't magically fix compute requirements. that graphic of fn1 and fn2 and compute is confusing.

personally never used clustering and the cluster module (we did that at haproxy lvl with containerised individual node processes), but I think that's exactly what he's saying, that the cluster module is the limitation (https://nodejs.org/api/cluster.html). not sure how they use it but it seems to imply requests being fully read in the cluster PID than passed to the workers
