Is golang fast?

In recent years, golang has become a very popular programming language, and many developers are using it to develop various applications. However, there is a question that has been bothering people, that is, how fast is golang? Below, we will discuss this issue.

First of all, we need to know the advantages of golang. Compared with other programming languages, golang has the characteristics of lightweight, high concurrency, and high efficiency. When dealing with high concurrency and large-scale requirements, golang has become the first choice of many developers. This is due to the concurrency mechanism naturally supported by golang, such as goroutine, etc., which has extremely high efficiency and performance advantages in concurrent execution.

Secondly, we need to know the performance of golang. In fact, the performance of golang will vary in different scenarios, but overall, golang has very good performance. Below, we will list some actual test data as a reference.

1. Network processing performance test

In terms of network processing, golang's performance is very excellent. The following is a set of test data, which are the performance of golang, node.js, Python and other languages ​​when processing HTTP requests. The tool used for the test is ApacheBench, the test time is 10 seconds, and the number of concurrent requests is 1000:

Language	Response time (ms)	Number of requests

As shown in the above table, golang performs very well under high concurrency conditions. It has the shortest response time when processing HTTP requests and can handle the largest number of requests.

CPU-intensive test

In terms of CPU-intensive testing, golang’s performance is also very commendable. The following is a test for calculating pi, which is implemented using golang, Java, Python and other languages. The test data is the time it takes to calculate 1 billion digits of pi:

To sum up, golang can show strong performance in different scenarios, and its advantages such as high concurrency, lightweight, and high efficiency are unmatched by other languages. Therefore, we can conclude that golang is a very fast programming language.
