Thank's Daniel,

> The list of modules is different. I don't think you can compare event and
prefork servers as if they should behave the same, even more if you have a
different list of modules. Consider in prefork each process is a worker,
 while on event processes are not workers, but threads of each process.

As I already commented on my answer to Dino, I didn’t really think a module
would cause this change in memory usage, which is why I haven’t dedicated
myself to disabling them one by one. But I was clearly wrong. Thank you
again too!

For me is new the ulimit command, I take a look in a near future.

Wow! The memory eater was security2 ...

With the module enabled (120-160MB per process) ...
# ps axo 'user rss cmd' | grep apache | grep -v "\(root\|grep\|tomcat\)"
www-data 121232 /usr/sbin/apache2 -k start
www-data 120596 /usr/sbin/apache2 -k start
www-data 156816 /usr/sbin/apache2 -k start
www-data 162668 /usr/sbin/apache2 -k start

With the module disabled (9-15MB per process) ...
# a2dismod security2
Module security2 disabled.
To activate the new configuration, you need to run:
  systemctl restart apache2
# systemctl restart apache2
# ps axo 'user rss cmd' | grep apache | grep -v "\(root\|grep\|tomcat\)"
www-data 10340 /usr/sbin/apache2 -k start
www-data  9764 /usr/sbin/apache2 -k start
www-data 14164 /usr/sbin/apache2 -k start
www-data 14220 /usr/sbin/apache2 -k start

Thank's for your answer Dino. That's enough for me.

I didn’t really think a module would cause this change in memory usage,
which is why I haven’t dedicated myself to disabling them one by one. But I
was clearly wrong. Thank you again.

For your information, my problem was understand why so much difference
between to systems because I want to optimize some parameters
like: ServerLimit, StartServers, MinSpareServers, MaxSpareServers,
MaxClients and MaxRequestsPerChild

I need to know the memory used per each Apache process to find
the MaxClients value.

Re: [users@httpd] Why so much difference in memory used per process in apache2 between two different systems

2021-05-17 Thread Daniel Ferradal

The list of modules is different. I don't think you can compare event and
prefork servers as if they should behave the same, even more if you have a
different list of modules. Consider in prefork each process is a worker,
while on event processes are not workers, but threads of each process.

In order to compare fairly you have to use the same modules, same load,
similar resulting mpm settings and compare the total usage, still your
biggest concern unless you have a faulty module mostly will be CPU.

Also consider there are some different modules in each case too, some are
third party modules.

MPM prefork is single threaded, while MPM event uses multiple threads,
and each thread "consumes" 8MB of rss (for its stack) on a typical
linux system.
The default thread stack size can be changed with "ulimit -s" (or
LimitSTACK= on systemd), depending on the loaded modules and their
stack "consumption".
I usually run httpd with "ulimit -s 512" (KB) without issues, but this
needs testing in your environment (i.e. no crash)..

Yann.

Try to comment out mod_security, it's a module that use enough memory.
Also on server2 there are modules not loaded on server1. BTW what's your 
problem? Your server is plenty of ram and RSS memory is not creating any

On Server2, each apache2 process uses between 120MB and 130MB of RAM ...

Why so much difference in memory used?

After read a few documentation and googleing, I thought about loaded
modules, but there are not a lot of difference between each server...

Server1
# apache2 -M

I already changed MPM mode from Event to Prefork on Server2, with the same
results.

What else can I check to understand this difference?

Thank's!
