The goroutine scheduler in Go distributes goroutines from the shared wait list using an M:N model, where M is the number of system threads (OS threads) and N is the number of goroutines.

Key points:

• Goroutines are placed in a queue of ready tasks (run queue).
• The scheduler assigns goroutines to available threads for execution.
• If a thread is busy, the scheduler can switch execution to another goroutine from the queue.
• The scheduler uses algorithms that consider load balancing and prevent goroutine starvation.

You can imagine it like this:

for {
    g := scheduler.getNextGoroutine()
    m := scheduler.getAvailableThread()
    m.run(g)
}

This way, the scheduler efficiently distributes goroutines across threads, ensuring concurrent execution and high performance.
