Vykon GSTIPE

[Tomas Randa]

Dobry den,

mel bych dotaz ohledne GEOM STRIPE. Mam v PC 80GB SATA disk, na kterem 
byla klasicka instalace FBSD 5.3. Ve volnem miste - 50GB jsem udelal 
dalsi slice. Pridal jsem druhy disk, udelal slice o stejne velikosti - 
50GB a udelal Geom Stripe prikazem:

gstripe label -h -v -s 4096 storage /dev/ad4s2c /dev/ad6s1c

vytvorilo mi to stripeset ktery podle diskinfo vypada velmi vykonne:

diskinfo -t /dev/stripe/storage
/dev/stripe/storage
        512             # sectorsize
        120204173312    # mediasize in bytes (112G)
        234773776       # mediasize in sectors

Seek times:
        Full stroke:      250 iter in   1.599289 sec =    6.397 msec
        Half stroke:      250 iter in   1.831418 sec =    7.326 msec
        Quarter stroke:   500 iter in   2.866551 sec =    5.733 msec
        Short forward:    400 iter in   3.078338 sec =    7.696 msec
        Short backward:   400 iter in   2.063029 sec =    5.158 msec
        Seq outer:       2048 iter in   0.579863 sec =    0.283 msec
        Seq inner:       2048 iter in   0.593848 sec =    0.290 msec
Transfer rates:
        outside:       102400 kbytes in   0.991848 sec =   *103242 
kbytes/sec*
        middle:        102400 kbytes in   1.086723 sec =    94228 kbytes/sec
        inside:        102400 kbytes in   1.448991 sec =    70670 kbytes/sec

Rekl jsem si proc nevyuzit vykon pro cely system, nuze zkopiroval jsem 
/usr /var a /tmp na tento oddil a ve fstab zmenil pripojovani /usr /var 
a /tmp misto UFS na NULLFS. Po restartu vse nabehne bez problemu, az na 
to, ze vykon celeho systemu je vice nez hrozny, napriklad start KDE trva 
hrozne dlouho atd.

Kde muze byt problem?

Diky za radu. Tomas Randa
