Hi, just to test I created two Centos 8 with apache and php, clean nothing more than update the kernel to 5.6.12
By default, on Centos 8, php is installed with php-fpm enable and configured.
To make Benchmark test I disable php-fpm on Server 1
Server 2 has enable php-fpm
Both servers show which version of php are using:
Server 1: Server API Apache 2.0 Handler
Server 2: Server API FPM/FastCGI

when I ran a simple ab test (ab -n 5000 -c 100 http://localhost:80/) I got the next results:

Server 1:
Requests per second: 1887.44 [#/sec] (mean)

As you can see, seems like php has better performance than php-fpm

Do anyone knows why? and how to improve better performance on php-fpm?
