Linux 4.15 I/O Scheduler Tests: BFQ, CFQ, Kyber
CFQ had another win when it came to FS-Mark.
While BFQ did the best with the BlogBench read performance...
While CFQ and None were the best for this Java-based BlogBench benchmark.
Lastly, the IOzone write performance was the highest with CFQ.
Overall, CFQ was doing the best but BFQ also had a fair share of wins. Paolo Valente has commented that they are working on further performance optimizations to BFQ that will appear in Linux 4.16~4.17, similar to the BFQ improvements as a result of our previous I/O scheduler benchmark results, so stay tuned for more Linux I/O tests to come.
