I was a very early adopter of cgroups right from 8.0
back in 2013, and
love 'em. I suspect you will too. At least a couple
of the cgroup bug tickets
originated with me, both at CHTC and Red Hat. ;D

They're really an essential element of exec node self-defense,
and
made a big difference in the uptime numbers back when
we were still working
on disciplining some of our misbehaving jobs.
