测试环境：
- 系统： CentOS 7.1
- Mem: 8G
- CPU: 虚拟机16核
- Python版本： python3.6
- Flask版本： 0.12.2
- Golang版本： 1.6.3
1.首先写一个Flask的web程序，只返回一个 Hello word!
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello word!'
if __name__ == '__main__':
app.run()2.写一个go语言的web程序，也返回一个 Hello word!
package main
import (
f "fmt"
"log"
"net/http"
)
func sayhelloName(w http.ResponseWriter, r *http.Request) {
f.Fprintln(w, "hello world!")
}
func main() {
http.HandleFunc("/", sayhelloName)
err := http.ListenAndServe(":8080", nil)
if err != nil {
log.Fatal("ListenAndServe:", err)
}
}3.直接在控制台启动Flask, 用压力测试工具模拟并发请求。这里模拟100个并发100000个请求。
