hi-nginx-javascript vs node.js

hi-nginx-1.4.9已经支持javascript，这意味着把javascript应用于后端开发，将不再只有nodejs这唯一的途径和方法。由于java本身对javascript的极好支持，使得在hi-nginx中，可以直接在javascript脚本中使用java——相当于把java嵌入了javascript。因此，你随时可以用java写个库或者类，然后在javascript中随便玩。这比用c/c++写node.js扩展舒服多了。

那么，hi-nginx-javascript VS node.js，如何呢？来个node.js (6.12.0)helloworld比较下。

fedora 25,4g,2core,i5,笔记本

node.js：

var http = require('http');

http.createServer(function (request, response) {

    // 发送 HTTP 头部
    // HTTP 状态值: 200 : OK
    // 内容类型: text/plain
    response.writeHead(200, {'Content-Type': 'text/plain'});

    // 发送响应数据 "Hello World"
    response.end('Hello World');
}).listen(8888);

// 终端打印如下信息
console.log('Server running at http://127.0.0.1:8888/');

hi-nginx-javascript:

        location / {
                hi_need_cache off;
                hi_cache_expires 5s;
                hi_need_kvdb on;
                hi_kvdb_size 10;
                hi_kvdb_expires 5s;
                hi_need_cookies on;
                hi_need_headers on;
                hi_need_session on;
                hi_session_expires 300s;
                hi_javascript_lang javascript;
                hi_javascript_extension js;
                #hi_javascript_script javascript/index.js;
                hi_javascript_content "hi_res.content='hello,world';hi_res.status=200;";
        }

使用ab作为压力测试工具:ab -c 1000 -n 500000。从最终稳定结果RPS来看，n=500000对nodejs来说是越不过去，

Completed 50000 requests
Completed 100000 requests
Completed 150000 requests
apr_socket_recv: Connection reset by peer (104)
Total of 162214 requests completed

而hi-nginx-javascript均值在14000多左右：

Server Software:        nginx/1.14.0
Server Hostname:        127.0.0.1
Server Port:            8086

Document Path:          /
Document Length:        11 bytes

Concurrency Level:      1000
Time taken for tests:   34.366 seconds
Complete requests:      500000
Failed requests:        0
Total transferred:      139000000 bytes
HTML transferred:       5500000 bytes
Requests per second:    14549.43 [#/sec] (mean)
Time per request:       68.731 [ms] (mean)
Time per request:       0.069 [ms] (mean, across all concurrent requests)
Transfer rate:          3949.94 [Kbytes/sec] received

把n降低至100000,nodejs偶尔能完成测试，RPS的最好成绩是8900多，其值在6000至9000间徘徊：

Server Software:
Server Hostname:        127.0.0.1
Server Port:            8888

Document Path:          /
Document Length:        11 bytes

Concurrency Level:      1000
Time taken for tests:   11.114 seconds
Complete requests:      100000
Failed requests:        0
Total transferred:      11200000 bytes
HTML transferred:       1100000 bytes
Requests per second:    8997.62 [#/sec] (mean)
Time per request:       111.141 [ms] (mean)
Time per request:       0.111 [ms] (mean, across all concurrent requests)
Transfer rate:          984.11 [Kbytes/sec] received

而hi-nginx-javascript则依然表现出众,与n=500000是差不多：

Server Software:        nginx/1.14.0
Server Hostname:        127.0.0.1
Server Port:            8086

Document Path:          /
Document Length:        11 bytes

Concurrency Level:      1000
Time taken for tests:   7.038 seconds
Complete requests:      100000
Failed requests:        0
Total transferred:      27800000 bytes
HTML transferred:       1100000 bytes
Requests per second:    14208.52 [#/sec] (mean)
Time per request:       70.380 [ms] (mean)
Time per request:       0.070 [ms] (mean, across all concurrent requests)
Transfer rate:          3857.39 [Kbytes/sec] received

结论：

hi-nginx-javascript 完胜 nodejs。
