Goroutines and Threads:1. Dynamic stack:1) Threads have a fixed-size block of memory (typically 2MB) to stack2) A goroutine will start its life cycle with a very small stack, usually only 2KB, not fixed; the stack size will dynamically scale as needed2.Goroutine Dispatch:1) threads are scheduled with a hardware timer, slow2) Go is using its own scheduler, scheduling on the thread basis, does not need to enter the kernel context3.GOMAXPROCS environment variables can determine how many threads are
