It appears (on OSX at least) the minimum number of threads a Go process will be 5. You need to understand that there are multiple threads for usually the following reasons: signal handling, GC collection, monitoring, OS events, timers, and others. The number of threads is going to vary based on number of CPUs in the system, and also the platform. GOMAXPROCS limits the number of OS threads used to run user level code, it does not control the number of threads used to run “internal/runtime” code.
