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())
}
```
