So they’ll have CPU and IO schedulers optimized for throughput instead of latency, meaning a laggy desktop under load. The whole virtual memory system still runs things like it is on spinning rust (multiple page files in cache, low swappiness, etc).

LOL. A Ken Colivas problem, circa 2008, still there :-)))
