詳解PHP7開啟OPcache和Swoole性能的提升對比

Posted on by

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。虛擬機系統為linux，http服務器采用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，在裡面新建一個test方法：

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

在routes/api.php中註冊一個路由：

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

在app/Http/Kernel文件中，關掉頻率限制中間件throttle。

不開啟opcache和laravel

修改php-fpm.conf文件，修改pm和pm.max_children 配置，pm設置為static，pm.max_children設置為50，以獲得較好的並發性能。

[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後用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

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

此時的並發大約為為 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後，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

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)

此時的達到瞭 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，將請求轉發到swoole監聽的端口。

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

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

速度起飛！達到瞭800qps！

也就是一百多倍？

總結

當然這隻是一個比較簡單的測試，但是總的來說opcache擴展和swoole擴展對php腳本性能的提升還是很明顯的。
