Laravel 在高并发下很卡？求大神解答

区内找到了这篇文章和我遇到的查不到，在执行index.php的时候开启php-fpm慢日志发现php-fpm执行时间长，导致php-fpm占用着cpu一直居高不下.
没有几个人回答，是因为这个问题不值得讨论？

其中查了curl_exec(),get_userinfo()发现他们在网站人数少的时候不会出现。
现在当在线人数300左右就一直很卡，php-fpm一直是在80以上.
4G4核服务器100M共享带宽撑不住500人即时在线访问。PHP-FPM一直高居不下

配置如下

Laravel5.4框架

PHP版本7.01

Mysql用2核2G的RDS

服务器CentOS7.2

cat /usr/local/php/etc/php-fpm.d/www.conf |egrep -v '^$|^;|^$'

#php-fpm 配置

cat /etc/nginx/nginx.conf| egrep -v '^;|^$|^#'

    include /etc/nginx/conf.d/*.conf;
}

百度的统计,在线人数303

图片上传不来，只能打表格，同志们，帮忙分析下？是php-fpm的配置不行还是laravel不适合做这种高并发的程序？
