Need suggestions - Running etcd as realtime process

[rajanarayanaa]

Is it advisable to run etcd as a realtime process using chrt?
Example chrt -p 60 <pid of etcd process> This is primarily to ensure etcd get enough CPU cycles on a system when it's loaded.
Could someone please advise me here?

Hey @rajanarayanaa - Thanks for your question. etcd is generally more sensitive to disk latencies rather than CPU contention from my experience.

When etcd is running on a system with competing workloads our tuning guidelines recommend the use of ionice to set disk priority, refer: https://etcd.io/docs/v3.5/tuning/#disk.

We don't currently have any written tuning documentation for etcd with chrt so if you do experiment with this please let us know how it goes.
