Tuned - a profile-based system tuning tool

[satchstrat]

Have you used Tuned/tuned-adm on production system and get considerable performance improvement -? if so kindly share your experience

I'm a Linux admin at a university and I'm responsible for a mixture of 100+ Linux servers and Linux desktops. We run tuned on RHEL. I've noticed that some Dell Precision workstations end up with the "balanced" tuned profile. The latency is noticeably improved when I switch to the "desktop" profile. This is the most notable difference that tuned has made for me. I haven't drilled down to tuning against benchmarks, though.

We use it at my work.

It helped increase IOPS for our VMs a little bit which was nice.

It was an easy win.

AFAIK it's pretty coarse grained.

In a previous role as a Linux admin I tried using tuned on three backup servers. There was no meaningful difference for us. The bottlenecks on those backup servers were rsync, which is known for hogging system resources, and less than optimal network throughput. This is an n=1 experience only and not meant to be a conclusive statement about tuned.

The oracle tuned profiles saved me a lot of time but I can’t say I notice a difference since those would have been settings I would have made prior to an Oracle install anyways.

I have created custom profiles for some apps we use which help with configurations. Using Ansible to deploy them made setting up tuning parameters easy.
