我正在测试 nodejs (0.8.11)。
使用以下服务器应用程序：
var http = require('http');
http.createServer(function (req, res) {
console.log('hit!');
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');
我运行了 apache 基准测试：
ab -r -v 4 'http://127.0.0.1:1337/'
我得到以下输出：
hit!
hit!
hit!
hit!
hit!
hit!
hit!
hit!
hit!
... (alot more)
ab的输出：

并且认为默认请求数不是 ab 手册中指定的 1，我尝试了：
ab -v 4 -n 1 -c 1 'http://127.0.0.1:1337/'
我得到相同的输出（日志中有很多“命中！”）
这里发生了什么？
这是特定于节点的，我已经用我的码头应用程序尝试过同样的ab -c 1 -n 1方法，只有 1 次记录命中......
注意：我尝试过卷曲节点服务 - 只有 1 次“命中！” 在日志中...
