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:

并认为默认的请求数不是1,如ab手册中所述,我试过:
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?
这是针对节点的,我用我的码头应用尝试了同样的问题ab -c 1 -n 1
,只记录了一次...
注意:我尝试过卷曲节点服务 - 只有1'命中!'在日志......

我还在nodejs google群组中发布了此内容。显然这是apache / ab的macosx lion版本中的一个错误。

每个'点击'都是新连接。从你的角度来看,为什么它看起来不对?
