Hey Daniel! Good to read you!
These parameters were suggested by @arighi in Fine-Tuning the Ubuntu 24.04 Kernel for low latency, throughput, and power efficiency, so they weren’t without forethought or previous discussion. Additionally, other discussions took place in Ubuntu 24.04 Boosts Gaming Performance.
For audio production, I’d absolutely prefer full over voluntary, but for gaming, as you can see, @luisalvarado is seeing some minor increases which, while minor, every little bit helps.
The other noteworthy piece was the power consumption decrease he noted in the previous post, so there’s definitely something to this beyond performance increase.
Either way, your echo full > /sys/kernel/debug/sched/preempt is something I’m going to be integrating into the Ubuntu Studio Audio Configuration wizard so that users don’t have to reboot for the command parameters to take effect, but can make the changes on-the-fly. I’m not sure if the other parameters can be done in a similar manner, but more research needs to be done on that front.
