机器：Macbook Pro CPU：8核 内存：16G SSD硬盘
测试工具：ab
测试并发：一共发送1000个请求 ，一共100个客户端 。
PS:本来想把并发数弄大一些，奈何只要调大了就会报错：apr_socket_recv: Connection reset by peer (54)，按照网上的资料说是ab的bug，把Apache重新安装就行，然后用新安装的ab替换旧的ab，然并卵。。 依然这个错误，所以就暂时先这样吧。
测试命令：
nginx：ab -n1000 -c100 -k http://localhost/test/index.php
workerman： ab -n1000 -c100 -k http://127.0.0.1:9999/
swoole：ab -n1000 -c100 -k http://127.0.0.1:9501/
nginx对应的 代码
|
1 2 3 |
<?php echo 'hello world'; |
workerman代码：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
<?php use Workerman\Worker; require_once './Workerman/Autoloader.php'; $worker = new Worker('http://0.0.0.0:9999'); $worker->onMessage = function($connection, $request) { $connection->send("hello world"); }; Worker::runAll(); |
swoole代码
|
1 2 3 4 5 6 7 |
<?php $http = new Swoole\Http\Server("127.0.0.1", 9501); $http->on('request', function ($request, $response) { $response->end("Hello world"); }); $http->start(); |
三个文件的代码都是最简单的输出hello world。

结果分析
每秒处理请求数 Requests per second:
nginx:7084.76
workerman:34917.24
swoole:65257.11
90%的客户端请求处理时间：
nginx：16毫秒
workerman：3毫秒
swoole:2毫秒
从这个结果可以看出来swoole的并发能力大概是nginx的9倍，是workerman的2倍（仅是当前测试环境，生产环境会有各种复杂的场景），由此可见swoole用来做web服务器比nginx和workerman性能高很多，稳定性就不清楚怎么样了。
疑问：nginx和workerman比swoole性能低的原因是什么？性能都消耗在哪里了？
