Some Fresh I/O Scheduler Benchmarks: Linux 4.13 With BFQ, CFQ, Kyber, Deadline

[Veto]

For a Linux sw development/multimedia/gaming pc, it looks like the deadline i/o scheduler still is the best choice for a ssd. I am wrong?

Well, to my eyes the "None" scheduler seems to have the best balance on a fast SSD...
KISS wins again

I think you have it backwards. Low-latency is responsive, high throughput has high-latency and is less responsive.

That does seem to make more sense.

Am I the only one looking at those graphs with absolutely no clue as to which scheduler is better?

From my understanding http://algo.ing.unimo.it/people/paolo/disk_sched/
BFQ is meant as a replacement for CFQ where load of a single application or thread won't hijack all throughput. Having a parallel load tester may be more beneficial to see than a straight single load.

I see no clear advantage. Sure it's better in some cases, but it's also worse in other cases...
