Fio (e emetse Flexible I/O Tester) e theha melapo ea disk I/O ho lekola ts'ebetso ea sistimi ea faele ea Linux. Sesebelisoa se ka tsamaisoa hape ho Windows - o hloka ho kenya sebopeho sa mola oa taelo . Tataiso ea ho seta e kene .
Mongoli fio - Jens Axbo (), bakeng sa tsamaiso e nyenyane ea IO ho Linux le moqapi oa lisebelisoa ho latela ts'ebetso ea I/O. O entse joalo, ngola mananeo ho leka meroalo e itseng ka letsoho.
Ts'ebeliso e tla bala IOPS le phallo ea sistimi, hape e u lumelle ho hakanya botebo ba mokoloko oa ts'ebetso ea I / O. Sesebelisoa se sebetsa ka lifaele tse khethehileng (.fio extension) moo litlhophiso le maemo a teko li boletsoeng. Ho na le likhetho tse 'maloa tsa tlhahlobo, mohlala, ho na le ho ngola ho sa reroang, ho bala le ho ngola holimo. Mona litaba tsa faele bakeng sa nyeoe ea pele:

Kajeno fio e sebelisoa ke lik'hamphani tse kholo - li sebetsa le lisebelisoa ho , и .
Sesebelisoa se ngotsoe ke moqapi oa Canada Mark Lord morao koana ka 2005. O ntse a le teng hape ke karolo ea liphatlalatso tse ngata tse tsebahalang. Morero o ka sehloohong oa hdparm ke ho lokisa li-parameter tsa drive. Empa sesebelisoa sebelisa bakeng sa litekanyetso tse bonolo, joalo ka lebelo la ho bala. Ho etsa sena, ngola taelo ho console:
$ sudo hdparm -t /dev/sdbSistimi e tla fana ka karabo e kang ena:
Timing buffered disk reads: 242 MB in 3.01 seconds = 80.30 MB/secHa e le ho lokisa li-drive, hdparm e u lumella ho fetola boholo ba memori ea cache, ho fetola mokhoa oa ho robala le litlhophiso tsa matla, hape u hlakole data ho SSD ka mokhoa o sireletsehileng. Empa joang Litsebi tse tsoang ho ArchLinux, liphetoho tse sa tsotelleng ho li-parameter tsa tsamaiso li ka etsa hore data ho disk e se ke ea fumaneha esita le ho senya koloi. Pele o sebetsa le hdparm, ho molemo ho bala bukana - kenya feela taelo ea man hdparm ho console.
Ena ke sete ea litekanyetso tsa ho lekola tšebetso ea litsamaiso tsa I/O. Bangoli ba ts'ebeliso e ne e ho tsoa ho sehlopha sa AlgoDev, se kenyelletsang basebetsi ba Mataliana .
Li-benchmarks tsohle ke mangolo a bash, ts'ebetso ea sistimi ea polokelo - phetisetso, latency, ts'ebetso ea kemiso. Ka mohlala, palo ea throughput-sync.sh "libomo" tsamaiso ea polokelo e nang le likopo tsa ho bala kapa ho ngola (tabeng ena, ho sebelisoa fio e seng e boletsoe). Mona .
Script e 'ngoe - comm_startup_lat.sh - e lekanya ho lieha ha ho bala data ho tswa ho disk ha cache e "bata" (ha e se na lintlha tse hlokahalang). Code hape .

Sesebelisoa sa ho lekola ts'ebetso ea sistimi ea faele, e ntlafalitsoeng ka 1989. Mongoli oa eona e ne e le moenjiniere Tim Bray. Ka thuso ea Bonnie o ile a rera ts'ebetso ea litsamaiso tsa likhomphutha tse amehang morerong ona Univesithing ea Waterloo.
Bonnie ho bala le ho ngola ka mokhoa o sa reroang ha data ho disk. Kamora moo, ts'ebeliso e bonts'a liparamente joalo ka palo ea li-byte tse sebetsitsoeng ka bonngoe , hammoho le boemo ba processor load e le peresente. Khoutu ea mohloli oa benchmark ea fumaneha .
Ho ipapisitsoe le Bonnie, ho hahiloe sete e 'ngoe ea lisebelisoa tsa ho lekola li-hard drive - (e ngotsoe ka C++ sebakeng sa C). E fana ka lisebelisoa tse eketsehileng tsa benchmark. Mohlala, zcav ho lekola ts'ebetso ea libaka tse fapaneng tsa HDD. Hape ke Bonnie++ bakeng sa ho hlahloba li-server tsa mangolo le li-server tsa database.
E ntlafalitse lisebelisoa (Con Kolivas), ngaka e robatsang ka lithethefatsi ea Australia e tsebahalang ka tlatsetso ea eona ho nts'etsopele ea kernel ea Linux mme e sebetsa ho "" Interbench e u thusa ho hlophisa kemiso ea I/O le litlhophiso tsa sistimi ea faele.
Interbench e etsisa boitšoaro ba mohlophisi oa CPU ha a etsa mesebetsi e kopanetsoeng. Mesebetsi ena e kopanetsoeng e ka sebetsa ka molumo le video, ho bapala lipapali tsa k'homphieutha, kapa ho hula lebokose la puisano tsamaisong ea ts'ebetso.
Khoutu ea mohloli, mehlala le likhothaletso tsa ho hlophisa sesebelisoa li ka fumanoa ho .
