multithreading - Number of threads used by Go runtime

Question

How many threads can the Go runtime (scheduler, garbage collector, etc.) use? For example, if GOMAXPROCS is 10, how many of those kernel threads would be used by the runtime?

Edit:

I was reading the rationale for changing GOMAXPROCS to runtime.NumCPU() in Go 1.5. There was a sentence that claimed that “the performance of single-goroutine programs can improve by raising GOMAXPROCS due to parallelism of the runtime, especially the garbage collector.”

My real question is: If I have a single-goroutine program running in a Docker container that has a CPU quota, what is the minimum number of logical processors that I need in order to have maximum performance?
