process with built-in PHP module cannot process static resources when processing PHP, and Nginx does not need to worry about this problem, because processing PHP is a PHP-FPM, this is static and dynamic separation. and Nginx supports upstream configuration PHP-FPM cluster load balancing, this is Apache is not good. PHP-FPM with Nginx can also separate I/O intensive operations to reduce the impact of blocking on the entire PHP application.User Download and curl requests are typical I/O-intensive
