Pike’s talks emphasize that concurrency is not the same as parallelism. Unfortunately for Go, CPUs are designed to exploit parallelism — in so many ways, that stack — so CSP-style concurrency comes with massive overhead when used on fine-grained problems like this. If you want performance, find parallelism and exploit it.
