There are downsides of course (no IPC) but I still argue that CPU is not the bottleneck for 99% of usage scenarios.
I suppose my experience might be unusual, but I frequently log in to c3.8xlarge redis machines that have a single core pegged at 100% and the rest doing nothing. Yes multiple processes help, but that requires updating clients and makes it harder to share memory.
To suggest that his product is a "dead end" due to not supporting threading seems a bit premature, as Redis and HAProxy are extremely well-regarded in their niche and they made it there without threading.
Well yeah, CPUs hitting their GHZ limit and the dramatic increase in the number of cores per machine is a relatively recent phenomena.
I just think its weird to start a brand new project making those same assumptions, especially when the underlying programming language was explicitly designed with concurrency in mind.
It'd be like building a new networking library in Rust which ditches memory safety.
