PHP7开启OPcache和Swoole哪个提升更大？性能的提升对比

这次测试咱们采用Laravel框架。laravel作为最热门的php框架之一，广受认可与欢迎。同时由于集成度很高，每次运行都加载了大量文件，加之使用了大量的闭包、魔术方法，导致laravel框架很重，并发性能极差。OPcache和Swoole都是php的扩展，这次旨在比较这两个扩展分别开启后对Laravel应用的加速效果。

 

前期准备

测试所用的主机为虚拟机，虚拟机配置在双核4GB的个人电脑中。虚拟机系统为linux，http服务器采用nginx，用lnmp脚本安装nginx、mysql、php。Laravel框架为7.X版本。

• 配置站点，在nginx的server块中配置虚拟主机

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

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; } }

　　

?

1 2	编辑/etc/hosts文件，在新行添加 127.0.0.1  test.laravel.com

　　

• 打开项目，新建控制器TestController，在里面新建一个test方法：

 

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

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

　　

• 在routes/api.php中注册一个路由：

?

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

　　

在app/Http/Kernel文件中，关掉频率限制中间件throttle。

 

不开启opcache和laravel

修改php-fpm.conf文件，修改pm和pm.max_children 配置，pm设置为static，pm.max_children设置为50，以获得较好的并发性能。

 

[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

• 重启fpm后用ab压测：ab -n 1000 -c 100 http://test.laravel.com/api/test

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

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 Complete requests:      1000 Failed requests:        0 Total transferred:      253000 bytes HTML transferred:       3000 bytes 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

　　

此时的并发大约为为 7 qps

（3）开启OPcache

在配置文件php.ini文件中开启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

• 重启fpm后，用ab压测：ab -n 1000 -c 100 http://test.laravel.com/api/test

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

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 Total transferred:      254000 bytes HTML transferred:       4000 bytes Requests per second:    90.86 [#/sec] (mean) Time per request:       1100.590 [ms] (mean) Time per request:       11.006 [ms] (mean, across all concurrent requests) Transfer rate:          22.54 [Kbytes/sec] received    Connection Times (ms)               min  mean[+/-sd] median   max Connect:        0    1   4.3      0      16 Processing:   409 1069 152.0   1092    1414 Waiting:      408 1069 152.0   1092    1414 Total:        424 1070 149.6   1092    1414    Percentage of the requests served within a certain time (ms)   50%   1092   66%   1126   75%   1149   80%   1162   90%   1203   95%   1242   98%   1280   99%   1309  100%   1414 (longest request)

　　

此时的达到了 90qps，性能是未开启时的 10 倍以上！。

（4）使用swoole加速包

开源的laravel-swoole加速包

在项目目录下运行composer命令安装；在nginx的配置文件中配置，将请求转发到swoole监听的端口。

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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

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:   1.158 seconds Complete requests:      1000 Failed requests:        0 Total transferred:      225000 bytes HTML transferred:       4000 bytes Requests per second:    863.46 [#/sec] (mean) Time per request:       115.813 [ms] (mean) Time per request:       1.158 [ms] (mean, across all concurrent requests) Transfer rate:          189.72 [Kbytes/sec] received

　　

 

速度起飞！达到了800qps！

也就是一百多倍？

(4)总结

当然这只是一个比较简单的测试，但是总的来说opcache扩展和swoole扩展对php脚本性能的提升还是很明显的。
