    So is that something I should do or not?!

    Hello :)

    Please see the description for this option:

    If mod_ruid2 is compiled in via EasyApache, mod_ruid2 is enabled, and a user has their shell set to jailshell or noshell, enabling this option will chroot() a user's Apache Virtual Host into the cPanel® jailshell environment. Each user will require 14 bind mounts. While modern Linux supports a very large number of bind mounts, many processes read /proc/mounts (even mkdir on RHEL 5 and CentOS 5). Reading /proc/mounts can be quite expensive when it becomes large. It is highly recommended that you do not exceed 256 jailed users unless you are using RHEL 6 or CentOS 6.

    I recommend verifying the OS version and the number of users on your system before enabling this option.

    Thank you.
