Hi,

In newer Centos-7 and apache 2.4.x, the mpm module used is defined in /etc/httpd/conf.modules.d/00-mpm.conf
So you can put your settings wherever you want, e.g. in /etc/httpd/conf/httpd.conf (like before), in /etc/httpd/conf.modules.d/00-mpm.conf, or create a new conf file /etc/httpd/conf.d/prefork.conf

From the httpd-mpm.conf file, that comes with 2.4.x source, defaults for each module are:
Code:
<IfModule mpm_prefork_module>
    StartServers             5
    MinSpareServers          5
    MaxSpareServers         10
    MaxRequestWorkers      250
    MaxConnectionsPerChild   0
</IfModule>
<IfModule mpm_worker_module>
    StartServers             3
    MinSpareThreads         75
    MaxSpareThreads        250
    ThreadsPerChild         25
    MaxRequestWorkers      400
    MaxConnectionsPerChild   0
</IfModule>
<IfModule mpm_event_module>
    StartServers             3
    MinSpareThreads         75
    MaxSpareThreads        250
    ThreadsPerChild         25
    MaxRequestWorkers      400
    MaxConnectionsPerChild   0
</IfModule>
