I’m wondering if Digital Ocean’s CentOS image is already optimized or do I need to run this line? tuned-adm profile virtual-guest

×DO CentOS doesn’t have tuned-adm installed by default, so I guess the answer is no. Also:
<^>All the profiles are stored in separate subdirectories under /etc/tune-profiles. So /etc/tune-profiles/desktop-powersave contains all the necessary files and settings for that profile. Each of these directories contains up to four files:
tuned.conf
the configuration for the tuned service to be active for this profile.
sysctl.ktune
the sysctl settings used by ktune. The format is identical to the /etc/sysconfig/sysctl file (refer to the sysctl and sysctl.conf man pages).
ktune.sysconfig
the configuration file of ktune itself, typically /etc/sysconfig/ktune.
ktune.sh
an init-style shell script used by the ktune service which can run specific commands during system startup to tune the system.<^>
So if there is no conf files in /etc/tune-profiles is probably is not enabled.
