PHP7開啓OPcache和Swoole哪一個提高更大？性能的提高對比

此次測試我們採用Laravel框架。laravel做爲最熱門的php框架之一，廣受承認與歡迎。同時因爲集成度很高，每次運行都加載了大量文件，加之使用了大量的閉包、魔術方法，致使laravel框架很重，併發性能極差。OPcache和Swoole都是php的擴展，此次旨在比較這兩個擴展分別開啓後對Laravel應用的加速效果。

 

前期準備

測試所用的主機爲虛擬機，虛擬機配置在雙核4GB的我的電腦中。虛擬機系統爲linux，http服務器採用nginx，用lnmp腳本安裝nginx、mysql、php。Laravel框架爲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，在裏面新建一個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。

 

不開啓opcache和laravel

修改php-fpm.conf文件，修改pm和pm.max_children 配置，pm設置爲static，pm.max_children設置爲50，以得到較好的併發性能。

 

[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

• 重啓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

　　

此時的併發大約爲爲 7 qps

（3）開啓OPcache

在配置文件php.ini文件中開啓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

• 重啓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

Transfer rate:          22.54 [Kbytes/sec] received
 
Connection Times (ms)
              min  mean[+/-sd] median   max

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)

　　

此時的達到了 90qps，性能是未開啓時的 10 倍以上！。

（4）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！達到了800qps！

也就是一百多倍？

(4)總結

固然這只是一個比較簡單的測試，可是總的來講opcache擴展和swoole擴展對php腳本性能的提高仍是很明顯的。
