Overall great article, applicable to other languages too.

I'm curious about the Goroutine pinning though:

    // Pin goroutine to specific CPU
    func PinToCPU(cpuID int) {
        runtime.LockOSThread()
        // ...
        tid := unix.Gettid()
        unix.SchedSetaffinity(tid, &cpuSet)
    }

The way I read this snippet is it pins the go runtime thread that happens to run this goroutine to a cpu, not the goroutine itself. Afaik a goroutine can move from one thread to another, decided by the go scheduler. This obviously has some merits, however without pinning the actual goroutine...
