���h oletkos n�hnyt/ajanut testej� (Byte/lmbench/tms)?
Ajoinpa viime viikolla meid�n rakenteilla olevassa
nyysiservossa (Intel 200MHz P6 Venus ATX, 256kb sis-cache
[IMHO sais olla 2MB]/128MB/12GB UWF-SCSI-II) muutamia testej�
ja olin pudota tuolilta!
Esim 2-prosessin context-switch 4�s, kahdeksalla 5�s,
muistista tuli tavaraa 228MBs ja sinne meni 83MBs,
levylle menee keskim��rin 7.5MBs ja sielt� tulee
keskim��rin 32.7MBs (cachesta) pienill� tiedostoilla,
isoilla tiedostoilla jolloin cache ei vaikuta vastaavat luvut
ovat 8.9MBs ja 10.8MBs. Hei, kyll� saa pilukihvit kohta kyyti�! ;)
Em. ilm. merkkaa sit� ett� yhdell� PCI-ethernet-sovittimella
tuskin selvit��n vaan niit� on oltava ainakin kaksi.
Feedille ja luu^H^H^Hreadereille oma, suoraan switchiin
kiinni. BTW, tiet��k� kukaan mik� on Linux-ATM projektin status?
Olispa kiva tuupata se samantien cellplexiin kiinni, kuuseen
koko eetteri :)
Ajaisin samat testit mielell�ni tuolla Elorannan huoneessa
lojuvassa 333MHz PC64-emosta kasattussa kapineessa kunhan
se saataisiin siihen vaiheeseen ett� testeiss� on jotain
mielt�, nyt siin� on niin lahna (tavallinen) 5GB levy ettei
se tee oikeutta sille, siis verrattuna nyt tehtyyn testiin,
mutta kyll� siin� vauhtia piisaa siit� huolimatta. Kiva
siirrell� kamaa sinne kun eetteri�kin pitkin tulee usein
tasaseen 7Mbps funetista, ncftp palkki vaan heilahtaa
vasemmalta oikealle, levy kurahtaa kerrran kernelin haun
j�lkeen syncist�...
Tarvis oikeestaan ajaa viel� n�� testit oldtimerissa (VAX 11/750)
niin vois elvistell� silkroadissa ;)
:-) riku
ps. Tulokset jos/kun joku haluaa kuitenkin tarkemmin...

IOZONE: Performance Test of Sequential File I/O -- V1.16 (10/28/92)
By Bill Norcott
Operating System: POSIX 1003.1-1988 -- using fsync()
Send comments to: norcott_bill@tandem.com
IOZONE writes a 256 Megabyte sequential file consisting of
524288 records which are each 512 bytes in length.
It then reads the file. It prints the bytes-per-second
rate at which the computer can read and write files.
Writing the 256 Megabyte file, 'iozone.tmp'...29.990000 seconds
Reading the file...24.780000 seconds
IOZONE performance measurements:
8950832 bytes/second for writing the file
10832746 bytes/second for reading the file
