That's not how the Go runtime works, I think? You shouldn't expect to see a 1:1 mapping of goroutines:OS processes. Quoting Russ Cox on the golang-nuts list: "This is a popular split but hardly the only definition of those terms. One reason we use the name goroutine is to avoid preconceptions about what those terms mean. For many people threads also connotes management by the operating system, while goroutines are managed first by the Go runtime" More here: https://medium.com/the-polyglot-programmer/what-are-goroutines-and-how-do-they-actually-work-f2a734f6f991 Are you actually seeing a problem (an actual problem, not "I can only see one line for my app in "top") specific to OpenBSD?
