[users@httpd] How do I choose the best settings for the Apache Server?
Hello,
My server has 6 GB RAM and 4 virtual CPUs. I want to know How can I change the following settings for better performance?
Timeout 45
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 15
<IfModule mpm_prefork_module>
StartServers 3
MinSpareServers 3
MaxSpareServers 3
ServerLimit 50
MaxClients 50
MaxRequestsPerChild 1000
</IfModule>
<IfModule mpm_worker_module>
StartServers 3
MaxClients 50
MinSpareThreads 3
MaxSpareThreads 3
ThreadsPerChild 25
MaxRequestsPerChild 1000
</IfModule>
I'm thankful if anyone can guide me to choose the above settings according to my server hardware specifications. If you know of other settings, please share.
Thank you.

Hello,Thanks again.So, is it better to use the following module?
<IfModule mpm_event_module> StartServers 3 MinSpareThreads 75 MaxSpareThreads 250ThreadLimit 64ThreadsPerChild 25MaxRequestWorkers 400 MaxConnectionsPerChild 0 </IfModule>
Do you know of any articles, websites, or something like a cheat sheet for quickly setting up Apache?

Use mod_status with ExtendedStatus on, and monitor /server-status to check how many idle workers you have, over time.

What is wrong with the default values? Why do you want to "estimate"?
Have you tried different values? If so, what was the upside/downside of
your trials? Logs? Stats?
You say somewhere below that your server "uses WordPress, so it also has
PHP and MySQL." Fine, these are services (memory and CPU cycles)
outside the scope of Apache/httpd which just "serves" what it is given
to "serve."
As an example, I have just rewritten a quite big (474 Gb) WP website in
html5 with minimal php and js. Result: client output identical, Apache
throughput just over 90% lower. YMMV
Good luck,
Paul

There are no "best" values, either way; it depends on your traffic pattern.
Use mod_status with ExtendedStatus on, and monitor /server-status to check
how many idle workers you have, over time.

You will need to ask the cpanel community in that case.

Hello,
In the Apache configuration file, there is the following text:
DO NOT EDIT. AUTOMATICALLY GENERATED. USE INCLUDE FILES IF YOU NEED TO MAKE A CHANGE
...
# /etc/apache2/conf.d/includes/pre_main_global.conf
# /etc/apache2/conf.d/includes/pre_virtualhost_global.conf
# /etc/apache2/conf.d/includes/post_virtualhost_global.conf
...
So because of cPanel, any changes I make are lost. In which of the above files should I apply the changes?

You can only load one mpm module at a time. Run apachectl -M to see the
loaded mpm.

When I probably recommended MaxSpareThreads == to MaxRequestWorkers was
due to Apache httpd with third party modules not restarting gracefully,
that along to MaxConnectionsPerChild 0 would prevent HTTPD from trying to
restart them.
Where did you get this?
Also I keep wondering why people assign so many processes, StartServers 16?
In a threaded mpm?
Why not just assign just 2 or even 4, and assign 100, 200 worker threads
each?

Not saying this is ideal but I went through an iterative set of confs

Hello,Thank you so much.Can you share an ideal Apache configuration file? Something like a template.

What is wrong with the default values? Why do you want to "estimate"?
Have you tried different values? If so, what was the upside/downside of
your trials? Logs? Stats?
You say somewhere below that your server "uses WordPress, so it also has
PHP and MySQL." Fine, these are services (memory and CPU cycles)
outside the scope of Apache/httpd which just "serves" what it is given
to "serve."
As an example, I have just rewritten a quite big (474 Gb) WP website in
html5 with minimal php and js. Result: client output identical, Apache
throughput just over 90% lower. YMMV
Good luck,
Paul

Hello,Thanks again.How about the other parameters? For example, how can I estimate the best value for "MaxRequestsPerChild", "ThreadsPerChild" and etc.?

There is no "template"; you just need to tweak event to spawn more workers if needed, but the default settings should be fine for small volumes.
The prefork mpm should really be avoided at this point, as it spawns a separate process for every single HTTP request.

Just comment out the LoadModule line for prefork, and uncomment the line
for event.
There is no "template"; you just need to tweak event to spawn more workers
if needed, but the default settings should be fine for small volumes.
The prefork mpm should really be avoided at this point, as it spawns a
separate process for every single HTTP request.

You'll want to make sure you're using the event mpm, in any case. It should
run well under 500MB even with thousands of workers.
If php or another dynamic language is involved, then the answer will depend
