Apache vhosts are not segmented

Hello, I am getting this warning when I run a security scan:

• Apache vhosts are not segmented or chroot()ed. Enable "Jail Apache" in the "Tweak Settings" area, and change users to jailshell in the "Manage Shell Access" area.

My question is, if I am running PHP-FPM service for Apache should I still install mod_ruid2 and then Jail Apache Virtual Hosts? Are they compatible, and in my case, necessary? Again, I run all sites on the server. Last, if the answer is that I should install this to beef up security, will this slow down my site speed?
