tuned tool from redhat is just for tunning kernel params, cpu gouvernor, ioscheduler, ... from profiles (high-bandwith vs low latency for example)

It's not related to ksm.

you can find details about the profils and tuning values here :

https://videos.cdn.redhat.com/summit2015/presentations/11952_performance-tuning-red-hat-enterprise-linux-platform-for-databases.pdf

(page 8).


Could be great to have something similar in proxmox. (should be east to implement), choosing in gui for each server, presets of tuning.



BTW, I have redone a lot of tests with transparent hugepage and last kernels, it seem to works fine with default MADVISE.
I have done tests with a lot of databases, redis, mongo  and I don't have seen any regression, and some boost with java application

OK, so we cannot recommend it...

But I have not found reasonable docs - why is is better? What features does 
it provide? Can it replace ksmtuned?
