C10K問題的解決，涌現出一大批新框架，或者新語言，那麼問題來了:到底誰最快呢？非專業程序猿來個非專業對比。html

比較程序：輸出Hello World！node

測試程序：siege –c 100 –r 100 –bpython

例子包括：git

1.go用http模塊實現的helloworldgithub

2.go用martini微框架實現的Helloworldgolang

3.python3 python2 pypy分別用gevent server tornado實現的Hello worldweb

4.python3 python2 pypy分別用微框架bottle+gevent實現的Hello worldexpress

5.NodeJS純JS實現的Helloworld服務器

6.NodeJS用express框架實現的Helloworldapp

測試平臺：

公司老舊的奔騰平臺 Pentium(R) Dual-Core CPU E6700 @ 3.20GHz

內存2GB（夠弱了吧）

先來宇宙最快的GO的測試：

  1 package main
  2 
  3 import (
  4         "fmt"
  5         "net/http"
  6 )
  7 
  8 func sayhelloName(w http.ResponseWriter, r *http.Request){
  9         fmt.Fprintf(w, "hello world!")
 10 }
 11 
 12 func main() {
 13         http.HandleFunc("/", sayhelloName)
 14         http.ListenAndServe(":9090", nil)
 15 }

連續測試5次，成績大致以下：

  1 Transactions:                  10000 hits
  2 Availability:                 100.00 %
  3 Elapsed time:                   4.11 secs
  4 Data transferred:               0.11 MB
  5 Response time:                  0.03 secs
  6 Transaction rate:            2433.09 trans/sec
  7 Throughput:                     0.03 MB/sec
  8 Concurrency:                   79.76
  9 Successful transactions:       10000
 10 Failed transactions:               0
 11 Longest transaction:            0.20
 12 Shortest transaction:           0.00

4.11秒，不錯的成績

再看NodeJS的例子：

  1 var http = require("http");
  2 http.createServer(function(request, response) {
  3     response.writeHead(200, {"Content-Type": "text/plain"});
  4     response.write("Hello World!");
  5     response.end();
  6 }).listen(8000);
  7 console.log("nodejs start listen 8888 port!");
  8

測試結果以下：

  1 Transactions:                  10000 hits
  2 Availability:                 100.00 %
  3 Elapsed time:                   5.00 secs
  4 Data transferred:               0.11 MB
  5 Response time:                  0.04 secs
  6 Transaction rate:            2000.00 trans/sec
  7 Throughput:                     0.02 MB/sec
  8 Concurrency:                   86.84
  9 Successful transactions:       10000
 10 Failed transactions:               0
 11 Longest transaction:            0.17
 12 Shortest transaction:           0.00

5秒，比Go稍微慢一點

接下來是Python，因爲python自帶的wsgiref服務器，只是一個參考實現，性能不好，因此這裏選用了兩個性能不錯的WSGI服務器gevent、tornado

gevent代碼以下：

  1 #!/usr/bin/python
  2 from gevent import pywsgi
  3 
  4 def hello_world(env, start_response):
  5     if env['PATH_INFO'] == '/':
  6         start_response('200 OK', [('Content-Type', 'text/html')])
  7         return ["hello world"]
  8 
  9 print 'Serving on https://127.0.0.1:8000'
 10 server = pywsgi.WSGIServer(('0.0.0.0', 8000), hello_world )
 11 server.serve_forever()
 12

tornado的代碼以下：

  1 from tornado import httpserver
  2 from tornado import ioloop
  3 def handle_request(request):
  4     if request.uri=='/':
  5         message = b"Hello World!"
  6         request.write(b"HTTP/1.1 200 OK\r\nContent-Length: %d\r\n\r\n%s" % (
  7                  len(message), message))
  8         request.finish()
  9 
 10 http_server = httpserver.HTTPServer(handle_request)
 11 http_server.bind(8888)
 12 http_server.start()
 13 ioloop.IOLoop.instance().start()
 14

因爲python的例子要分別在python2 python3 pypy下跑，結果太多，我這裏只給結果：

gevent：

python2：5.8秒，python3：7.5秒，pypy：4.8秒

有意思的是：pypy第一次跑用了6.8秒，第二次之後全是4.8秒（感受緣由是第一次因爲jit浪費了一點時間）貼出某次pypy的成績：

  1 Transactions:                  10000 hits
  2 Availability:                 100.00 %
  3 Elapsed time:                   4.77 secs
  4 Data transferred:               0.10 MB
  5 Response time:                  0.04 secs
  6 Transaction rate:            2096.44 trans/sec
  7 Throughput:                     0.02 MB/sec
  8 Concurrency:                   90.38
  9 Successful transactions:       10000
 10 Failed transactions:               0
 11 Longest transaction:            0.13
 12 Shortest transaction:           0.00
 13

接下來是tornado：

python2：9.05秒，python3：8.6秒，pypy：5.95秒

一樣：pypy第一次執行的時間爲9.45秒，之後的每次只執行時間爲5.9秒多一些

能夠看出，pypy 與go nodejs性能至關，其中go最快爲4.11秒，pypy+gevent與nodejs性能差很少，pypy稍好一點，pypy+tornado則稍慢於nodejs。

2。框架篇：

從上邊例子能夠看到，純代碼寫起來仍是比較麻煩的，通常咱們都是用框架來寫web，我選了幾個輕量級的框架來輸出helloworld：

go+martini

  1 package main
  2 
  3 import "github.com/codegangsta/martini"
  4 
  5 func main() {
  6   m := martini.Classic()
  7   m.Get("/", func() string {
  8     return "Hello world!"
  9   })
 10   m.Run()
 11 }
 12

運行時間爲：

  1 Transactions:                  10000 hits
  2 Availability:                 100.00 %
  3 Elapsed time:                   4.69 secs
  4 Data transferred:               0.11 MB
  5 Response time:                  0.04 secs
  6 Transaction rate:            2132.20 trans/sec
  7 Throughput:                     0.02 MB/sec
  8 Concurrency:                   90.23
  9 Successful transactions:       10000
 10 Failed transactions:               0
 11 Longest transaction:            0.17
 12 Shortest transaction:           0.00
 13

nodejs+express：

  1 var express = require('express')
  2 var app = express()
  3  
  4 app.get('/', function (req, res) {
  5   res.send('Hello World')
  6 })
  7  
  8 app.listen(3000)

用時：

  1 Transactions:                  10000 hits
  2 Availability:                 100.00 %
  3 Elapsed time:                   5.90 secs
  4 Data transferred:               0.10 MB
  5 Response time:                  0.06 secs
  6 Transaction rate:            1694.92 trans/sec
  7 Throughput:                     0.02 MB/sec
  8 Concurrency:                   96.44
  9 Successful transactions:       10000
 10 Failed transactions:               0
 11 Longest transaction:            0.13
 12 Shortest transaction:           0.01
 13

python gevent+bottle：

  1 from gevent import monkey
  2 monkey.patch_all()
  3 from bottle import run,get
  4 
  5 @get("/")
  6 def index():
  7     return "Hello world!"
  8 
  9 run(server='gevent')
 10

用時：python2 10.05秒，python3：12.95秒，pypy：5.85秒

python tornado：

  1 import tornado.httpserver
  2 import tornado.ioloop
  3 import tornado.web
  4 
  5 class IndexHandler(tornado.web.RequestHandler):
  6     def get(self):
  7         self.write('Hello World!')
  8 
  9 if __name__ == "__main__":
 10     app = tornado.web.Application(handlers=[(r"/",IndexHandler)])
 11     http_server = tornado.httpserver.HTTPServer(app)
 12     http_server.listen(8000)
 13     tornado.ioloop.IOLoop.instance().start()
