Most people do not understand the knowledge points of this article "what are the differences between go language and swoole", so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this article, "what are the differences between go language and swoole?"

Differences: 1, the go language uses single-threaded eventloop to handle IO events, while swoole uses multithreaded eventloop to handle IO events; 2, the golang language layer supports multithreading, but the swoole language layer does not support multithreading; 3. The go language has hyperglobal variables, but swoole does not have hyperglobal variables.

Operating environment of this tutorial: Windows10 system, Swoole4&&GO version 1.11.2, DELL G3 computer

The difference between golang and swoole

1. About language

Golang uses static language, is troublesome to write, has high single efficiency, and is mostly used for io-intensive computing.

Swoole php is dynamically interpreted and executed, and its language performance is poor, so it is not suitable for intensive computing programs.

2. About IO

Golang uses single-threaded eventloop to handle IO events, and multi-threaded cooperative scheduling to run user code

Swoole uses multithreaded eventloop to handle IO events, and multiple processes execute user code

3. About the cooperative process

The golang language layer supports multithreading, and using multithreading scheduling protocols, stack file symbol sharing can be realized, but it is easy to cause data interference, which requires locking mechanism when in use.

The swoole language layer does not support multithreading, and single thread is used to achieve cooperative scheduling, and there is no data interference for each thread.

4. About the operation mode

Golang is multithreaded, with super-global variables, data interference and data sharing.

Swoole is a multi-process operation, there are no hyperglobal variables, only process-level variables, no data interference problems, you have to use table to achieve data sharing

The above is about the content of this article on "what are the differences between go language and swoole". I believe we all have a certain understanding. I hope the content shared by the editor will be helpful to you. If you want to know more about the relevant knowledge, please follow the industry information channel.
