Comparing the performance of Golang and Python: Which one is more efficient?

Performance comparison between Golang and Python: Who is better?

With the rapid development of the software development industry, it has become particularly important to choose a programming language that is both efficient and applicable. This article will discuss the performance comparison of two popular programming languages, Golang and Python, aiming to help readers understand the advantages of the two in different aspects so as to make the right choice for their needs. In order to demonstrate the comparison results more concretely, this article will provide several code examples for comparison.

First, let’s take a look at the basic performance indicators of Golang and Python. Golang is a programming language designed for high-performance web servers and concurrent applications. It is known for its excellent concurrency capabilities and excellent performance. On the other hand, Python, as an interpreted language, is widely used in fields such as web development, data science, and machine learning.

We first compare the performance of the two languages ​​on CPU-intensive tasks. The following is a code example for calculating the Fibonacci sequence:

Golang code example:

package main

import "fmt"

func fibonacci(n int) int {
    if n <= 2 {
        return 1
    } else {
        return fibonacci(n-1) + fibonacci(n-2)
    }
}

func main() {
    result := fibonacci(30)
    fmt.Println(result)
}

Python code example:

def fibonacci(n):
    if n <= 2:
        return 1
    else:
        return fibonacci(n-1) + fibonacci(n-2)

result = fibonacci(30)
print(result)

For calculating the Fibonacci sequence this CPU For intensive tasks, the performance of Golang can significantly exceed that of Python. In the environment I tested, the Python version of the code took about 9 seconds to complete the calculation, while the Golang version took less than 1 second. This simple example reveals the superior performance of Golang on CPU-intensive tasks.

Next, we compare the performance of the two languages ​​on IO-intensive tasks. Here is a code example to get the web content from the URL:

Golang code example:

package main

import (
    "fmt"
    "io/ioutil"
    "net/http"
)

func main() {
    resp, _ := http.Get("https://www.example.com")
    defer resp.Body.Close()
    body, _ := ioutil.ReadAll(resp.Body)
    fmt.Println(string(body))
}

Python code example:

import requests

response = requests.get('https://www.example.com')
print(response.text)

For this IO-intensive task, both The performance difference is not huge. In the tests I conducted, both took nearly the same amount of time to complete the task. This is because in IO-intensive tasks, the processing time of network requests is often the bottleneck of the task, rather than the programming language itself.

In addition to performance comparisons, other features and uses of the two languages ​​also need to be considered. Golang shines in the field of network development and concurrent programming with its simplicity, efficiency and reliability. Python is popular for its simplicity and ease of learning, rich third-party libraries, and wide range of application scenarios.

To sum up, Golang has obvious advantages in CPU-intensive tasks, while it is not much different from Python in IO-intensive tasks. Therefore, when choosing a programming language, we should weigh the required performance and other factors based on actual needs. If you need high performance and concurrent programming capabilities, Golang is a good choice; if you need rapid development and a wide range of application scenarios, Python may be more suitable.

In short, there is no perfect programming language, only the most appropriate programming language that can meet specific needs. I hope the comparison in this article can help readers better understand the performance differences between Golang and Python, so as to make the right choice.
