快捷導(dǎo)航

詳解PHP7開啟OPcache和Swoole性能的提升對比

laravel作為最熱門的php框架之一，廣受認可與歡迎。同時由于集成度很高，每次運行都加載了大量文件，加之使用了大量的閉包、魔術(shù)方法，導(dǎo)致laravel框架很重，并發(fā)性能極差。OPcache和Swoole都是php的擴展，這次旨在比較這兩個擴展分別開啟后對Laravel應(yīng)用的加速效果。

前期準備

測試所用的主機為虛擬機，虛擬機配置在雙核4GB的個人電腦中。虛擬機系統(tǒng)為linux，http服務(wù)器采用nginx，用lnmp腳本安裝nginx、mysql、php。Laravel框架為7.X版本。

配置站點，在nginx的server塊中配置虛擬主機

server{ listen 80; root "/vagrant/www/laravel7/public"; server_name test.laravel.com; index index.html index.php; location / { try_files $uri $uri/ /index.php?$args; } location ~ \.php$ { fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_index index.php; fastcgi_split_path_info ^(.+\.php)(.*)$; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }

編輯/etc/hosts文件，在新行添加127.0.0.1 test.laravel.com

打開項目，新建控制器TestController，在里面新建一個test方法：

<?php
namespace App\Http\Controllers;
 
 
 
class TestController extends Controller
{
    public function test()
    {
    	return 123;
    }
 
    
}

在routes/api.php中注冊一個路由：

Route::get('test', 'TestController@test');

在app/Http/Kernel文件中，關(guān)掉頻率限制中間件throttle。

不開啟opcache和laravel

修改php-fpm.conf文件，修改pm和pm.max_children 配置，pm設(shè)置為static，pm.max_children設(shè)置為50，以獲得較好的并發(fā)性能。

[www] listen = /tmp/php-cgi.sock listen.backlog = -1 listen.allowed_clients = 127.0.0.1 listen.owner = www listen.group = www listen.mode = 0666 user = www group = www pm = static pm.max_children = 50 pm.start_servers = 10 pm.min_spare_servers = 10 pm.max_spare_servers = 20 request_terminate_timeout = 100 request_slowlog_timeout = 0 slowlog = var/log/slow.log

重啟fpm后用ab壓測：ab -n 1000 -c 100 http://test.laravel.com/api/test

Server Software: nginx

Server Hostname: test.laravel.com

Server Port: 80

Document Path: /api/test

Document Length: 3 bytes

Concurrency Level: 100

Time taken for tests: 148.306 seconds

Failed requests: 0

Requests per second: 6.74 [#/sec] (mean)

Time per request: 14830.553 [ms] (mean)

Time per request: 148.306 [ms] (mean, across all concurrent requests)

Transfer rate: 1.67 [Kbytes/sec] received

此時的并發(fā)大約為為 7 qps

開啟OPcache

在配置文件php.ini文件中開啟opcache

zend_extension="opcache.so" opcache.enable=1 opcache.memory_consumption=128 opcache.max_accelerated_files=10000 opcache.revalidate_freq=60 opcache.fast_shutdown=1 opcache.enable_cli=1 opcache.interned_strings_buffer=8

重啟fpm后，用ab壓測：ab -n 1000 -c 100 http://test.laravel.com/api/test

Server Software: nginx

Server Hostname: test.laravel.com

Server Port: 80

Document Path: /api/test

Document Length: 4 bytes

Concurrency Level: 100

Time taken for tests: 11.006 seconds

Complete requests: 1000

Failed requests: 0

Transfer rate: 22.54 [Kbytes/sec] received

95% 1242

98% 1280

99% 1309

100% 1414 (longest request)

此時的達到了 90qps，性能是未開啟時的 10 倍以上！。

使用swoole加速包

開源的laravel-swoole加速包

在項目目錄下運行composer命令安裝；在nginx的配置文件中配置，將請求轉(zhuǎn)發(fā)到swoole監(jiān)聽的端口。

用 ab 壓測： ab -n 1000 -c 100 http://test.laravel.com/api/test

Server Software: nginx

Server Hostname: test.laravel.com

Server Port: 80

Document Path: /api/test

Document Length: 4 bytes
