Π takataura nezve yakavhurika sosi maturusi ekuongorora processor uye ndangariro kuita. Nhasi tiri kutaura nezve mabhenji emafaira masisitimu uye masisitimu ekuchengetedza paLinux - Interbench, Fio, Hdparm, S uye Bonnie.

Fio (inomirira Flexible I/O Tester) inogadzira dhisiki I/O hova kuti iongorore mashandiro eLinux faira system. Iyo yekushandisa inogona zvakare kumhanya paWindows - iwe unofanirwa kuisa iyo yekuraira mutsara interface . The setup guide iri mukati .
Munyori fio - Jens Axbo (), yeIO subsystem muLinux uye utility developer kutsvaga mashandiro eI/O. Akasika zviyo, nyora zvirongwa kuti uedze mitoro chaiyo nemaoko.
Iyo yekushandisa ichaverenga IOPS uye system throughput, uye zvakare inobvumidza iwe kuti ufungidzire kudzika kwemutsara weI/O mashandiro. Chishandiso chinoshanda nemafaira akakosha (.fio extension) umo marongero uye mamiriro ebvunzo anotsanangurwa. Pane akati wandei bvunzo sarudzo, semuenzaniso, pane zvisina kujairika kunyora, kuverenga uye kunyora pamusoro. Here faira zviri mukati kekutanga:
[global]
name=fio-rand-read
filename=fio-rand-read
rw=randread
bs=4K
direct=0
numjobs=1
time_based=1
runtime=900
Nhasi fio inoshandiswa nemakambani makuru - anoshanda neiyo utility in , ΠΈ .
Iyo yekushandisa yakanyorwa neCanada mugadziri Mark Lord kumashure muna 2005. Iye achiri uye chikamu chekugovera kwakawanda kwakakurumbira. Chinangwa chikuru chehdparm ndechekugadzirisa dhiraivha paramita. Asi mudziyo shandisa mabhenji akareruka, akadai sekumhanya kwekuverenga. Kuti uite izvi, nyora murairo mune console:
$ sudo hdparm -t /dev/sdbIyo sisitimu inoburitsa mhinduro seizvi:
Timing buffered disk reads: 242 MB in 3.01 seconds = 80.30 MB/secKana zviri zvekugadzirisa madhiraivha, hdparm inokutendera kuti uchinje saizi yecache memory, shandura yekurara modhi uye magetsi marongero, uye zvakare kudzima zvakachengeteka data paSSD. Asi sei Nyanzvi kubva kuArchLinux, shanduko dzisina hanya kune masisitimu ma paramita anogona kuita kuti data riri padhisiki risasvikiki uye kunyange kukuvadza dhiraivha. Usati washanda ne hdparm, zviri nani kuverenga bhuku racho - ingoisa mutemo man hdparm mune console.
Iyi seti yemabhenji ekuongorora mashandiro eI/O masisitimu. Vanyori vekushandisa vaive kubva kuboka reAlgoDev, rinosanganisira vashandi veItaly .
Ese mabhenji mabhash scripts, kuchengetedza system performance - throughput, latency, scheduler performance. Semuenzaniso, iyo throughput-sync.sh bhenji "mabhomba" sisitimu yekuchengetera ine kuverenga kana kunyora zvikumbiro (munyaya iyi, iyo yatotaurwa fio utility inoshandiswa). Here .
Imwe script - comm_startup_lat.sh - inoyera latency yekuverenga data kubva kudhisiki kana cache "inotonhora" (kana isina data inodiwa). Code zvakare .

Chishandiso chekuongorora faira system performance, yakagadzirwa muna 1989. Munyori wayo aive mainjiniya Tim Bray. Achibatsirwa naBonnie akaronga kushanda kwemakomputa masisitimu anobatanidzwa muprojekiti paYunivhesiti yeWaterloo.
Bonnie kuverenga nekunyorwa kwe data kune disk. Pashure utility inoratidza parameters senge nhamba yemabhayiti akagadziriswa pa , pamwe neiyo processor load level sechikamu. Benchmark source code iripo .
Zvichienderana naBonnie, imwe seti yezvishandiso zvekuyedza hard drive inovakwa - (yakanyorwa muC ++ pachinzvimbo cheC). Inopa mamwe mabhenji maturusi. Semuenzaniso, zcav kuongorora kushanda kwenzvimbo dzakasiyana dzeHDD. Uyewo Bonnie++ yekuyedza maseva etsamba uye maseva e database.
Yakagadzirwa utility (Con Kolivas), wekuAustralia anesthetist anozivikanwa nekupa kwake mukusimudzira Linux kernel uye anoshanda pa "" Interbench inokubatsira kugadzirisa I/O scheduler uye faira system marongero.
Interbench inotevedzera maitiro eCPU scheduler paunenge uchiita mabasa anodyidzana. Aya mabasa anodyidzana anogona kunge achishanda neodhiyo nevhidhiyo, achimhanyisa mitambo yemakomputa, kana kungodhonza dialog box musystem yekushandisa.
Source kodhi, mienzaniso uye kurudziro yekumisikidza chishandiso inogona kuwanikwa mukati .
