Milline on erinevus Go goruotini ja operatsioonisüsteemi tasemel süsteemilõime vahel?

Goroutines in Go and system threads (threads) differ in several key aspects:

• Lightweight: Goroutines are much lighter in resources than system threads. Thousands of goroutines can run simultaneously with minimal memory usage, whereas system threads require much more memory and resources.

• Scheduling: Goroutines are scheduled by Go's runtime (user-level scheduler), not by the operating system. This allows Go to efficiently switch between goroutines without the cost of system calls.

• Multiplexing: Many goroutines can operate on a smaller number of system threads. Go's runtime distributes goroutines across threads, optimizing CPU usage.

• Synchronization and communication: Goroutines typically interact via channels, which simplifies synchronization and data exchange, while system threads use lower-level mechanisms (mutexes, semaphores).

Therefore, goroutines are lightweight, language-managed threads that provide high scalability and efficiency compared to system threads.
