Difference between Goroutine and Thread in Golang.
Goroutine
Goroutine is method/function which can be executed independently along with other goroutines. Every concurrent activity in Go language is generally terms as gorountine.
Thread
Thread is a lightweight process. It can be treated as a unit to execute a piece of code. Operating system manages the thread.
Following are the important differences between Goroutine and Thread.
| Sr. No. | Key | Goroutine | Thread |
|---|
| 1 | Managed By | Goroutine methods are managed by golang runtime. | Thread are managed by operating systems. |
| 2 | Hardware dependency | Goroutine are independent to hardware. | Thread are dependent on hardware. |
| 3 | Communication Medium | Goroutines uses channels as communication medium. | Thread have no easy communication medium. |
| 4 | Latency | Goroutines can commuicate with other routines with low latency. | Thread as have no communication medium, communicate with other thread with high latency. |
| 5 | ID | Goroutine does not have any thread local storage and no unique id. | Thread have thread local storage and have unique id. |
| 6 | Scheduling | Goroutines are co-operatively scheduled. | Threads are preemptively scheduled. |
| 7 | Startup | Goroutines have faster startup time. | Threads have slower startup time. |
| 8 | Stack | Goroutines have growable segmented stacks. | Threads do not have growable segmented stacks. |
