壓測Laravel5.8、ThinkPHP5、Yii2
（1）測試環境搭建
這裏用virtualbox搭建Linux虛擬機，用vagrant管理虛擬機。Web服務器用nginx，可以用lnmp腳本安裝和管理nginx、php、mysql。
（2）配置站點
在nginx配置文件的server塊中配置虛擬主機。
配置laravel5.8項目
server{
listen 80;
root "/vagrant/www/laravel5.8/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;
}
}
配置yii2項目
server{
listen 80;
root "/home/wwwroot/yii2/web";
server_name test.yii2.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;
}
}
配置thinkphp5項目
server{
listen 80;
set $root /vagrant/www/myshop/public;
#root /vagrant/shop/public;
server_name test.tp5.com;
location / {
root $root;
index index.html index.php;
if ( -f $request_filename) {
break;
}
if ( !-e $request_filename) {
rewrite ^(.*)$ /index.php/$1 last;
break;
}
}
location ~ .+\.php($|/) {
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_split_path_info ^((?U).+.php)(/?.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $root$fastcgi_script_name;
include fastcgi_params;
}
}
配置完後，保存，命令行運行service nginx reload使配置生效。
（3）壓測
這裏在每個框架中定義一個路由，都路由到控制器中，控制器中只是簡單echo一個字符串’HELLO’，不做其他處理。然後命令行輸入ab命令壓測：
shell > ab -n 1000 -c 100 url

（4）分析和對比
可以看到在併發請求下，laravel框架的性能明顯比tp5和yii2差要差一些。總共發起1000次請求，每次100個併發請求，，三個框架的qps對比：
| 框架 | qps |
|---|---|
| Laravel5.8 | 8.12 |
| ThinkPHP5 | 65.94 |
| Yii2 | 36.92 |
造成這種結果的原因，是每個框架啓動過程中加載的資源不同。如果你研究過laravel的啓動過程，會發現laravel在完成一次請求的過程中加載（require）了大量的類文件，做了很多驗證、過濾、加密操作。這些操作會消耗更多內存，同時也會使完成一次請求的耗時更長。有利有弊，用laravel寫php代碼確實效率很快、代碼優雅，但卻犧牲了相當一部分性能。如果對併發性能有較高要求，建議用tp5做接口，tp5相對laravel更輕量。
（5）用swoole擴展加速laravel？
輪子已經有人造好了，laravel-s。有時間再測測。
