Session ID: HKG18-416 Session Name: HKG18-416 - I’m BFQ, I’m dynamite (or almost …) Speaker: Paolo Valente Track: Kernel
Session Summary
BFQ has greatly improved over the last months. Now it handles I/O at up to 400+ KIOPS with commodity CPUs, and extends its close-to-optimal responsiveness guarantees on any single-queue storage medium, from eMMC to fast SSDs. In this presentation we show these improvements, and:
- show how the work ‘around’ BFQ also influenced the benchmarking arena: from the consolidation of a responsiveness (application start-up time) test in the Phoronix benchmark suite, to the entry of the same test in the MMtests suite;
- prove the good match between BFQ and the new blk-mq support in mmc (Ulf&Linus; work), with demos and graphs;
- provide an update on the status of the proposal of BFQ as the default I/O scheduler for all single-queue storage;
- list the next important challenges for letting BFQ enter the server&cloud; world too.
