swoole是c/c++寫的網(wǎng)絡(luò)通訊擴(kuò)展，workerman是純php寫的網(wǎng)絡(luò)框架，兩者功能類似。我看到網(wǎng)上很多評論說swoole性能比workerman高不少，甚至還看到知乎有說workerman和swoole比不在一個(gè)數(shù)量級的。但是為什么我的壓測結(jié)果卻不是這樣，不管是我的mac pro還是剛剛阿里云服務(wù)器，二者性能差不多甚至有時(shí)workerman要比swoole壓測性能高一些？以下是我的壓測腳本和結(jié)果。

環(huán)境 阿里云：Ubuntu 18.04.3 LTS; 4核 4G；php7.2；swoole 4.4.15; workerman 3.4.24;

swoole 壓測腳本：

<?php
$http = new swoole_http_server("127.0.0.1", "1234");
$http->set(array(
    'worker_num' => 4, 
    'daemonize' => false, 
));
$http->on('request', function ($request, $response) {
    $response->end("hello");
});
$http->start();

workerman 壓測腳本：

<?php
require_once __DIR__ . '/workerman/Autoloader.php';
use Workerman\Worker;
$worker = new Worker('http://0.0.0.0:12345');
$worker->count = 4;
$worker->onMessage = function($connection, $data) {
        $connection->send('hello');
};

二者性能基本相近，沒有特別大的區(qū)別。有興趣的可以自己試下上面的壓測腳本，看看結(jié)果是不是和我一致。
