回复： PHP Performance/Scal ability

I think PHP-FPM had heavily reduce the concurrency of PHP. PHP should immediately implement a API like WSGI/ASGI in python. It is very simple but very useful. ------------------&nbsp;原始邮件&nbsp;------------------ 发件人: "Deepak Goel" <deicool@gmail.com&gt;; 发送时间:&nbsp;2021年10月26日(星期二) 晚上11:15 收件人:&nbsp;"Alex"<al-php@none.at&gt;; 抄送:&nbsp;"php-general General List"<php-general@lists.php.net&gt;;"Deepak Sharma"<deepak@techxp.tech&gt;; 主题:&nbsp;Re: PHP Performance/Scalability Hi The code is fairly simple. It contains a few images and a simple SQL query (The same code in Java gives superb performance). We have an Apache Web Server in front of php as of now. And I will try out this (https://github.com/spiral/roadrunner). Thanks.

The question is how "simple" is the PHP Code? Maybe you can tune the Code or use another Server in front of PHP FPM like haproxy, Caddy, nginx? Maybe you can try to run https://github.com/spiral/roadrunner to execute the PHP Code.
