Go 同步发HTTP请求是不是要比Python慢很多？

Go 新手，最近想测试下用Go 发HTTP的速度，所以就写了个脚本测试了下，同时发两个请求，跟Python对比了下，发现慢了很多， Python 使用aiohttp耗时0.14s，Go版本的耗时 0.29s，慢了2倍 按理讲如果Go的速度不快的话，那至少也是跟Python差不多的嘛， 为什么会差这么多，是我写的方式不对吗？求指教。 Go 和 Python 代码如下： ``` import time import aiohttp import asyncio async def fetch(session, url): async with session.post(url) as response: return await response.text() async def main(url): async with aiohttp.ClientSession() as session: html = await fetch(session, url) return html if __name__ == '__main__': t = time.time() loop = asyncio.get_event_loop() urls = [ "https://sina.com.cn", "https://news.baidu.com" ] tasks = [main(url) for url in urls] responses = loop.run_until_complete(asyncio.gather(*tasks)) for response in responses: print(response) print(time.time() - t) ``` ``` package main import ( "fmt" "io/ioutil" "net/http" "time" ) func MakeRequest(client http.Client, url string, ch chan<- string) { reqest, _ := http.NewRequest("GET", url, nil) response, _ := client.Do(reqest) body, _ := ioutil.ReadAll(response.Body) ch <- string(body) } func main() { start := time.Now() urls := []string{"https://sina.com.cn", "https://news.baidu.com"} client := &http.Client{} ch := make(chan string) for _, url := range urls { go MakeRequest(*client, url, ch) } for range urls { fmt.Println(<-ch) } fmt.Printf("%.8fs elapsed\n", time.Since(start).Seconds()) } ```
