com'e' che se do:
Code:
bash-2.05b# hdparm -tT /dev/hda
lui mi risponde con
Code:

/dev/hda:
could not allocate sharedmem buf: Function not implemented
could not allocate sharedmem buf: Function not implemented
8O 8O 8O
eppure il sistema nn e' lento...bah...stranezze..

P.S: mi sono agganciato qui x' mi sembrava un *simil-problema* un po' irrilevante x aprire un altro post :wink:


Ho risolto questo problema leggendo un post da qualche parte, devi abilitare l'opzione del kernel System V IPC che trovi sotto General Setup

Uhm... In poche parole mi stai dicendo di lasciar perdere?

Assolutamente no: ti sto dicendo che il problema nn e' da cercare sull'harddisk... e MyZelf forse ha azzeccato il problema...

Ciao!
Ho risolto il mio prob (grazie etilico :wink:).
questo il mio output:
Code:
/dev/hde:  <-- 60 GB Maxtor (ATA133)
 Timing buffer-cache reads:   2092 MB in  2.00 seconds = 1044.59 MB/sec
 Timing buffered disk reads:  140 MB in  3.01 seconds =  46.58 MB/sec
/dev/hdf: <-- 80 GB Maxtor (ATA133)
 Timing buffer-cache reads:   2084 MB in  2.00 seconds = 1041.64 MB/sec
 Timing buffered disk reads:  120 MB in  3.02 seconds =  39.74 MB/sec
/dev/hdg: <-- 60 GB Maxtor (ATA133)
 Timing buffer-cache reads:   2084 MB in  2.00 seconds = 1042.16 MB/sec
 Timing buffered disk reads:  142 MB in  3.02 seconds =  47.04 MB/sec
/dev/hdh: <-- 80 GB Maxtor (ATA133)
 Timing buffer-cache reads:   2100 MB in  2.00 seconds = 1048.59 MB/sec
 Timing buffered disk reads:  150 MB in  3.02 seconds =  49.64 MB/sec
Questo con kernel 2.6.0-test11, ma anche con il 2.4.22 le prestazioni nn calano; nn ho ancora fatto i test veri e propri, ma l'occhio e' il miglior test e nn sono di certo + lenti :wink:
A questo punto mi vien da pensare ad un problema hardware, vedi incompatibilita' tra chipset della scheda madre e quello della scheda, nn conosco la piastra che hai tu (ma essendo roba proprietaria, gia' mi fa paura :wink:) prova se puoi a spostare di slot la scheda, e' probabile che la scheda raid utilizzi lo stesso irq del canale ide o d qlcs'altro e probabilmente la scheda madre nn lo digerisce molto bene....Fai un po' di prove con i vari slot se possibile e facci sapere :lol:

Di niente ;) ... i miei valori sempre con un maxtor da 60 giga sono molto inferiori :(((((

Timing buffer-cache reads: 876 MB in 2.00 seconds = 438.00 MB/sec
Timing buffered disk reads: 144 MB in 3.02 seconds = 47.68 MB/sec


io ho il kernel 2.4.20 gentoo-source r9

Al caricare del kernel viene attivato con UDMA 133 ... questo è un pezzetto del caricamento del kernel, qualcuno a qualche suggerimento???
