Throttle runs first request with a delay

[freefelt]

I set throttle for every 3 seconds, but have a delay for 3 seconds for the first request. Was it intended that way?

        print("\(Date().toString(format: "HH:mm:ss")): Begin")
        for i in 1...10000 {
            throttle(.seconds(3)) {
                print("\(Date().toString(format: "HH:mm:ss")): throttle: \(i)")
            }
        }
