配置

这是lua block的nginx/openresty配置，openresty的版本1.19.3.1：

worker_processes 1;
error_log logs/error.log;
events {

    worker_connections 1024;
}
http{
    server {
        listen 6699;

        location / {
            default_type text/html;
            content_by_lua_block {
                ngx.say("<h1>HelloWorld</h1>");
            }
        }
    }

}

这是php的部分nginx/openresty配置, php版本是7.4.14：

    location ~ \.php$ {
        try_files $uri =404;
        include fastcgi.conf;
        fastcgi_pass   unix:/dev/shm/php7-fpm.sock;
    }
   ...

PHP 脚本：hello.php

<?php
echo '<h1>Hello hkhost</h1>';

测试结果：

lua block

ab -w -c10 -n50000 http://hkhost:6699/

============= 

PHP脚本

ab -w -c10 -n50000 http://hkhost/hello.php

并发差距非常明显，每秒处理的请求数 12000 对 5600 ，差距几乎达到2倍之大！

在openresty的官网对比页中，差距更高达4倍之多，当然他对比的是 5.2时代的 PHP，性能肯定更弱一些。

So on my laptop, for a single nginx worker, we've got 20k+ r/s. For comparison, HelloWorld servers using nginx + php-fpm 5.2.8 gives 4k r/s, Erlang R14B2 raw gen_tcp server gives 8k r/s, and [[node.js|http://nodejs.org/] v0.4.8 yields 5.7k r/s.
