Golang cannot write the system

The reason why Golang cannot become an operating system writing language

With the development of microservices and cloud computing, Go language (hereinafter referred to as Golang) has become more and more popular in modern software development. Golang has the advantages of rapid development, high efficiency, simplicity and ease of learning, and strong parallelism. It is widely used in web and backend development scenarios. However, some people think that Golang is not suitable for writing operating systems. This idea has attracted a lot of attention and discussion. So, why can’t Golang become an operating system writing language? Let’s explore it together.

1. Golang’s automatic memory management mechanism

Golang adopts an automatic memory management mechanism, which is garbage collection. This is a good choice for most situations because it makes memory management simple and easy to use. However, when writing operating systems, "easy-to-use" features often bring performance losses and controllability issues. The garbage collection mechanism needs to traverse the entire heap to find and remove objects that are no longer used, and this operation will have a serious impact on performance in scenarios such as the operating system.

In addition, the operating system needs to be very detailed and precise in controlling memory, and needs to directly control the allocation and recycling of memory. Therefore, the automatic memory management mechanism is not suitable for scenarios like the operating system.

2. Golang's running environment

Golang's running environment is based on threads (goroutine) and is managed by the Go runtime. This model can achieve high concurrency in web servers, but there is no such need in scenarios such as operating systems. In the operating system, the operating environment needs to directly control hardware resources such as processors, memory, and I/O devices, so a more efficient, precise, and controllable model is needed.

3. Lack of support for underlying operations

Golang provides some support for underlying operations, but these supports are only simple encapsulation of certain operations. Golang is an object-oriented programming language that emphasizes code readability and maintainability, so its support for underlying operations is not sufficient.

The operating system needs to directly operate the hardware, manage processes, implement interrupts and other operations. These operations require direct access to the underlying hardware to improve performance and controllability. But Golang's design philosophy is contrary to this. Therefore, Golang is not suitable for writing operating systems.

4. Limited Suitable Scenarios

Although Golang cannot be used to write an operating system, it still has features that are widely applicable to many fields such as web backend and concurrent processing. advantage. In these scenarios, Golang's concurrency model and automatic memory management mechanism can greatly simplify programming tasks and improve development efficiency.

In summary, although Golang is a powerful and efficient programming language, it is not suitable for writing operating systems. Automatic memory management mechanism, operating environment, support for underlying operations, etc. will cause performance and controllability problems, which the operating system cannot tolerate. However, in suitable scenarios, Golang can still show its talents and provide extremely high development efficiency and concurrent processing capabilities.
