I'm sorry to insist ... if this list is not the right place to ask that question, could anyone tell me where to do it? 

Thank's

Hi, I want to configure an apache server to support a high load site. Are these settings correct? 

/etc/apache2/mods-enabled/mpm_event.conf

<IfModule mpm_event_module>
        StartServers                     2
        MinSpareThreads          75
        MaxSpareThreads          250
        ThreadLimit                      64
        ThreadsPerChild          25
        MaxRequestWorkers         1500
        MaxConnectionsPerChild   0
        ServerLimit 75
</IfModule>

I used a combination of https://httpd.apache.org/docs/2.4/en/mod/mpm_common.html and https://support.plesk.com/hc/en-us/articles/214529205-Apache-keeps-going-down-on-a-Plesk-server-server-reached-MaxRequestWorkers-setting ...

MaxRequestWorkers = (Total RAM - Memory used for Linux, DB, etc.) / average Apache process size
=>
1500 = (64000 - 60000) / 40

The default ServerLimit value is 16. To increase it, you must also raise MaxRequestWorkers using the following formula: ServerLimit value x 25 = MaxRequestWorkers value. For example, if ServerLimit is set to 20, then MaxRequestWorkers will be 20 x 25 = 500.
=>
75 x 25 = 1500



The hardware includes 64GB of memory, AMD Ryzen 7 PRO 3700 8-Core Processor and NVME disks.

I'm using Apache 2.4.41 with event MPM on ubuntu 20.04 ...
