Jens Axboe, skaberen af io_uring og input\/output-planl\u00e6ggere som CFQ, Deadline og Noop, har fortsat sine eksperimenter med optimering af input\/output i Linux-kernen. Denne gang er det input\/output-planl\u00e6ggerne BFQ og mq-deadline, der er blevet en flaskehals, is\u00e6r n\u00e5r det g\u00e6lder hurtige NVMe-lagringsenheder. <\/p>\n

En unders\u00f8gelse af situationen har vist, at en af hoved\u00e5rsagerne til den suboptimale ydeevne i input\/output-planl\u00e6gningssystemerne skyldtes problemer med konkurrentl\u00e5sninger (\u2018lock contention\u2019, hvor en tr\u00e5d fors\u00f8ger at opn\u00e5 en l\u00e5s, der holdes af en anden tr\u00e5d). Takket v\u00e6re tiltag, der har til form\u00e5l at reducere konkurrencen om l\u00e5seh\u00e5ndtering, s\u00e5som seriel dispatchering og inds\u00e6ttelse af anmodninger, er hastigheden for planl\u00e6ggere steget betydeligt i flere situationer (m\u00e5lt i IOPS). <\/p>\n

Ved test af BFQ-planl\u00e6ggeren med v\u00e6rkt\u00f8jet fio steg ydeevnen fra 567K til 1551K input\/output-operationer per sekund, og l\u00e5se-konkurrencen faldt fra 96% til 30%. For mq-deadline blev ydeevnen efter anvendelse af de foresl\u00e5ede patches med en NVMe-lagringsenhed forbedret fra 1070K til 2560K input\/output-operationer per sekund (IOPS), mens l\u00e5se-konkurrencen faldt fra 94% til 23%.
