本文主要是介绍net8 golang python性能比较,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
net8正式版出来两个月,现在性能到底如何呢,做个简单的例子和其他语言比较一下,测试内容是查找1000000以内的质数,代码不多,但包含了循环计算和Math库函数调用,直观的看一下语言之间差距是多少,心里有个底,测试机是笔记本surface book 2 intel i7 有个四五年了,不过还能跑
首先来看看google的王牌语言golang,语法简单但性能号称不输C++,先看一下go 1.20.2
package mainimport ("fmt""math""time"
)func isPrime(num int) bool {if num <= 1 {return false}for i := 2; i <= int(math.Sqrt(float64(num))); i++ {if num%i == 0 {return false}}return true
}func countPrimes(n int) int {count := 0for i := 2; i < n; i++ {if isPrime(i) {count++}}return count
}func main() {num := 1000000startTime := time.Now()result := countPrimes(num)endTime := time.Now()fmt.Printf("The number of prime numbers less than %d is: %d\n", num, result)fmt.Printf("Execution time: %v\n", endTime.Sub(startTime))
}
编译之后看看耗时是多少
然后看看net6
using System;
using System.Diagnostics;namespace FindPrimeNet6
{class Program{static bool IsPrime(int num){if (num <= 1){return false;}for (int i = 2; i <= Math.Sqrt(num); i++){if (num % i == 0){return false;}}return true;}static int CountPrimes(int n){int count = 0;for (int i = 2; i < n; i++){if (IsPrime(i)){count++;}}return count;}static void Main(string[] args){int num = 1000000;Stopwatch timer = Stopwatch.StartNew();int result = CountPrimes(num);timer.Stop();Console.WriteLine($"The number of prime numbers less than {num} is: {result}");Console.WriteLine($"Execution time: {timer.ElapsedMilliseconds:F4} ms");}}
}
运行一下看看
然后重头来了net8 开启aot怎么样呢
看来速度没提升,应该是启动速度提高了
然后我们再看看大家心目中最慢的python,装了3.11.7版本
#import numba
import math
import time#@numba.jit
def is_prime(num):if num <= 1:return Falsefor i in range(2, int(math.sqrt(num)) + 1):if num % i == 0:return Falsereturn True#@numba.jit
def count_primes(n):count = 0for i in range(2, n):if is_prime(i):count += 1return countnum = 1000000
start_time = time.perf_counter()
result = count_primes(num)
end_time = time.perf_counter()time_elapsed = end_time - start_timeprint(f"The number of prime numbers less than {num} is: {result}")
print(f"Execution time: {time_elapsed*1000:.4f}ms")
看看普通模式跑跑要多少毫秒
竟然3秒7 是golang10倍,然后让我们开了jit再跑一次
看起来 并没有差前两个语言很多
然后打包exe再执行一次 差强人意哈哈 就这样吧,将就用,希望能给大家一个参考
