The Erlang processes don't care if they are hosted in a single OS process or multiple processes or even multiple host machines. It's not possible to write a high-performance program without a good understanding of the costs of primitives. If something might vary in cost by several orders of magnitude, it's quite hard to design for. Network transparency has never been a good fundamental for well-performing application architecture. Networks are inherently far less reliable than shared memory, and have massively more latency, particularly on the tail end of the distribution.
