swoole常驻内存性能优势

安装swoole

下载安装最新版本swoole 4.2.13

# 下载
wget https://github.com/swoole/swoole-src/archive/v4.2.13.tar.gz

# 解压进入
tar -xzvf v4.2.13.tar.gz
cd swoole-src-4.2.13

# 编译参数：
./configure  --with-php-config=/usr/local/php/bin/php-config --enable-openssl --enable-http2 --enable-sockets --enable-mysqlnd

# 安装
make & make install

# 加入php.ini
extension=swoole.so

# php.ini disable_functions中去掉以下函数
proc_open, proc_get_status

安装压测工具webbench

局域网内另外一台服务器上安装webbench

# 安装ctag先
yum install ctags

wget http://blog.s135.com/soft/linux/webbench/webbench-1.5.tar.gz

tar zxvf webbench-1.5.tar.gz

cd webbench-1.5

make && make install

目录结构

1. 创建项目目录tsr_test
2. composer安装 "respect/validation"
3. 创建swooloe_server.php和normal.php

composer init

composer require "respect/validation"

编写常规代码 normal.php

<?php
/**
 * Created by PhpStorm.
 * User: shyandsy
 * Date: 2/21/2019
 * Time: 1:45 AM
 */

require_once(__DIR__ . '/vendor/autoload.php');
use Respect\Validation\Validator as V;

try{
    //$this
    $validator = V::create()
        ->key('user', V::email())
        ->key('pass', V::alnum()->length(8, 32))
        ->key('token', V::alnum()->length(1));

    $validator->assert($_GET);

    $email = (string)$_GET['user'];
    $pass = (string)$_GET['pass'];
    $token = (string)$_GET['token'];

}catch(Respect\Validation\Exceptions\NestedValidationException $e){

}
echo 111;

编写swoole版本

<?php
/**
 * Created by PhpStorm.
 * User: shyandsy
 * Date: 2/21/2019
 * Time: 1:44 AM
 */
require_once(__DIR__ . '/vendor/autoload.php');
use Respect\Validation\Validator as V;

$http = new swoole_http_server("127.0.0.1", 9000);

$http->on('start', function ($server) {
    echo "Swoole http server is started at http://127.0.0.1:9000\n";
});

$http->on('request', function ($request, $response) {

    try{
        //$this
        $validator = V::create()
            ->key('user', V::email())
            ->key('pass', V::alnum()->length(8, 32))
            ->key('token', V::alnum()->length(1));

        $validator->assert($request->get);

        $email = (string)$request->get['user'];
        $pass = (string)$request->get['pass'];
        $token = (string)$request->get['token'];

    }catch(Respect\Validation\Exceptions\NestedValidationException $e){

    }

    $response->header("Content-Type", "text/plain");
    $response->end("111\n");
});

$http->start();

数据汇总

• swoole_server.php

• normal.php

• 对比

• 总结

1. 本测试中swoole_server.php没有经过nginx代理，相比normal.php少一个环节
2. swoole_server.php只需要一次加载respect/validator，而normal每次都要加载。本测试中仅仅是加载了respect/validator，实际项目中我们会用到很多组件，每次重复加载都会耗费cpu，swoole的优势会更加明显。
