And I forgot to mention that approach I mentioned talks about waking up N goroutines at a time. The way I plan to do is to select a range of N goroutines from my list of goroutines and only allow those goroutines to send HTTP requests. I could use this approach to select the N goroutines or even use a Semaphore. I presume using a Semaphore, will allow a good amount of random N goroutines out of M goroutines to execute.
