Daily Go Language Bible-goroutines and threading

Goroutines and Threads:

1. Dynamic stack:

1) Threads have a fixed-size block of memory (typically 2MB) to stack
2) A goroutine will start its life cycle with a very small stack, usually only 2KB, not fixed; the stack size will dynamically scale as needed

2.Goroutine Dispatch:

1) threads are scheduled with a hardware timer, slow
2) Go is using its own scheduler, scheduling on the thread basis, does not need to enter the kernel context

3.GOMAXPROCS environment variables can determine how many threads are started to execute the go code at the same time
4.goroutine No concept of identity (ID) that can be acquired by the programmer
