This article mainly explains "what are the differences between swoole and go". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what are the differences between swoole and go?"

Differences: 1. Go protocol is based on multi-threading and can make use of multi-core CPU, while swoole protocol is based on single thread, so it is not necessary to declare the environment of multi-core CPU;2 and go protocol, while swoole protocol must be used in the context of co-program.

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

What is the difference between swoole protocol and go protocol?

The Go language level supports the collaborative process, and there is no need to declare the collaborative process environment. Swoole must be used in the context of the collaborator.

Go is based on multi-thread and can utilize multi-core CPU,Swoole. The protocol is based on single thread and cannot take advantage of multi-core CPU.

Coroutines is a more lightweight existence than threads, just as a process can have multiple threads, a thread can have multiple collaborators. The collaborative process has the following characteristics

User mode execution is completely controlled by the program and is not managed by the operating system kernel

It is suitable for dealing with IO-intensive tasks. As for what is IO-intensive tasks, we will not elaborate here, which is mainly different from CPU-intensive tasks.

Convert the competitive resources in the thread into collaborative running

Communication between protocols by means of channel (Channel)

A small amount of context switching overhead is mainly run on the thread, while the context switch of the contrast process is saved in the stack resource, while the protocol is asynchronous and non-blocking, which is equivalent to the queue task in the user mode thread. It only needs to use channel as the callback, and there is no need for secondary resource grabbing after the task is completed.

Next, let's talk about the differences between swoole and Go protocols in detail.

Swoole cooperation program

Swoole's co-program client must be used in the context of the co-program.

Swoole's protocol is based on a single thread, cannot make use of multi-core CPU, and only one is scheduled at a time.

Example and detailed explanation of the use of Swoole Cooperative Program

The Cooperative Program goroutine of Go

Goroutine is a lightweight thread, and the Go language supports native protocols at the language level.

Compared with threads, the overhead of Go protocol is very small.

The stack overhead of Go protocol only uses 2KB, which can be increased and reduced according to the needs of the program.

The thread must specify the size of the stack, and the size of the stack is fixed.

Thank you for your reading, the above is the content of "what are the differences between swoole and go". After the study of this article, I believe you have a deeper understanding of the difference between swoole and go, and the specific use needs to be verified in practice.
