Subject Re: [users@httpd] MPM Modules Rule of Thumb
Date Wed, 06 Sep 2017 05:30:27 GMT
Hi Tony,

usually httpd consumes a very little amount of memory, if it is behaving in
that way it is probably due to some module like mod_php. Can you give us a
bit more info about your mpm used and the list of modules loaded? For
example, the most common use case that we see is mpm-prefork and mod_php
causing a ton of RAM consumed (each httpd process allocates memory for a
PHP interpreter), meanwhile a solution like mpm-worker|event +
mod_proxy_fcgi + php-fpm works way better.

My suggestion would be to narrow down what module is really causing your
memory to saturate before tuning the mpm.
