Ciao ragazzi, ho installato gentoo 2gg fa, e mi piace davvero tanto, in + mi permette di imparare un sacco di cose nuove sul pinguino, il che non guasta mai! 
Qualcuno sa spiegarmi come mai ottengo un punteggio così alto ? (Almeno credo sia alto da quello che ho visto in altri posts)
| Code: | /dev/hde:
Timing buffer-cache reads: 1732 MB in 2.00 seconds = 864.83 MB/sec
Timing buffered disk reads: 172 MB in 3.01 seconds = 57.11 MB/sec
|
mentre per un altro mio hdd sembra + normale:
| Code: |
/dev/hda:
Timing buffer-cache reads: 1804 MB in 2.00 seconds = 901.24 MB/sec
Timing buffered disk reads: 102 MB in 3.04 seconds = 33.51 MB/sec
|
Non mi è chiaro come mai i miei non compaiano 128 e 64 come sul mio PC con la SlackWare e lo stesso identico comando. Qualcuno mi sa spiegare plz ?
Grazie anticipatamente. |

Ah, se qualcuno è interessato, questo è il mio hde, l'hdd che ha quel punteggio altissimo a mio avviso.
| Code: |
bash-2.05b# hdparm -i /dev/hde
/dev/hde:
Model=Maxtor 6Y080L0, FwRev=YAR41BW0, SerialNo=Y24V5TGE

CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=156250000
IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4

UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6

Visto la magnificienza del tuo HDD (2Mb di cache dual-port, WriteCache enabled, UDMA6) mi sembrano valori normali... e da invidiare...
