What is the difference between go language and swoole

Difference: 1. The go language uses a single-threaded eventloop to handle IO events, while swoole uses a multi-threaded eventloop to handle IO events; 2. The golang language layer supports multi-threading, while the swoole language layer does not support multi-threading; 3. Go language has super global variables, but swoole does not have super global variables.

The difference between golang and swoole

1. About the language

golang uses a static language, which is troublesome to write, has high single efficiency, and is mostly used for io-intensive calculations
swoole php is a dynamic interpretation The language performance is poor and not suitable for intensive computing programs

2. About IO

golang uses a single-threaded eventloop to process IO events and multi-threaded coroutine scheduling to run User code
swoole uses multi-threaded eventloop to handle IO events, and multiple processes execute user code

3. About coroutines

Golang language level supports multi-threading, use Multi-threaded scheduling coroutine can realize stack file character sharing, but it is easy to cause data interference and requires a locking mechanism when using it.
The swoole language layer does not support multi-threading, and uses a single thread to implement coroutine scheduling. The data of each thread is There is no data interference alone.

4. About the running mode

golang is multi-threaded, has super global variables, has data interference problems, and can share data

swoole is When running in multiple processes, there are no super-global variables, only process-level variables, and there is no data interference problem. You have to use tables to share data yourself
