[administration][performance_tuning] IO Scheduler #1075

Open LukeShortCloud opened 5 months ago

LukeShortCloud commented 5 months ago

Benchmarks of schedulers do not show the real-world benefits.

Best I/O schedulers to prevent stuttering when using the desktop:

Despite benchmarks showing that "none" has the best performance (second being "kyber"), it does not showcase the latency or responsiveness of the system.

Arch Linux also recommends BFQ for flash drives and slow devices for a more responsive system.

I've been doing some testing and benchmarking for this. Kyber is best for NVMe drives specifically. Everything else (SSDs, HDDs, flash drives, SD cards, etc.) should use BFQ.
