UJens Axboe, umdali we-io_uring kunye ne-CFQ, i-Deadline, kunye nabacwangcisi be-Noop I/O, waqhubeka novavanyo lwakhe ngokulungiswa kwe-in-kernel I/O. LinuxNgeli xesha, ingqalelo yakhe yawela kwi-BFQ kunye nabacwangcisi be-I/O bexesha elimiselweyo le-mq, nto leyo eyathi yaba yingxaki, ubuncinane kwii-drive ze-NVMe ezikhawulezayo.
Njengoko uphononongo lwemeko lubonisiwe, esinye sezizathu eziphambili zokusebenza kwe-suboptimal performance ye-I / O scheduler subsystems yayiyiengxaki zokukhiya okukhuphisanayo ("ingxabano yokutshixa", inzame yokufumana isitshixo esibanjwe ngomnye umsonto). Siyabulela kumanyathelo ajolise ekunciphiseni ingxabano yokutshixa, njengokulandelelana kokuthunyelwa kunye nokufakwa kwemibuzo, isantya sabacwangcisi siye sanda kakhulu kwiimeko ezininzi (kwi-IOPS).
Xa uvavanya umcwangcisi we-BFQ nge-fio utility, ukusebenza kunyuke ukusuka kwi-567K ukuya kwi-1551K IOPS, kwaye ingxabano yokutshixa yehla ukusuka kwi-96% ukuya kwi-30%. Kwimeko ye-mq-deadline, ukusebenza emva kokufaka iipatches ezicetywayo xa usebenzisa i-NVMe drive yanda ukusuka kwi-1070K ukuya kwi-2560K ye-input / output operations ngesekhondi (IOPS), kwaye ingxabano yokukhiya iyancipha ukusuka kwi-94% ukuya kwi-23%.
