Hi!

Решил заняться тонким тюнингом своего HDD.

Исходные данные:

* MB: ASUS TUSL2-C (i815)
* HDD: IBM DTLA-305030 (5400 RPM)

Сейчас он сконфигурирован следующим образом:

$ sudo hdparm /dev/hda
Password:

/dev/hda:
 multcount    = 16 (on)
 I/O support  =  3 (32-bit w/sync)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 3737/255/63, sectors = 60036480, start = 0
 busstate     =  1 (on)

Тест на чтение, выполненный в runlevel 1:

# hdparm -tT /dev/hda

/dev/hda:
 Timing buffer-cache reads:   128 MB in  1.01 seconds =126.73 MB/sec
 Timing buffered disk reads:  64 MB in  2.16 seconds = 29.63 MB/sec

Настройки:

$ cat /etc/sysconfig/harddisk/hda
USE_DMA=1
MULTIPLE_IO=16
EIDE_32BIT=1
LOOKAHEAD=1
EXTRA_PARAMS=-X69u1c3

$ sudo hdparm -i /dev/hda

/dev/hda:

 Model=IBM-DTLA-305030, FwRev=TW3OA60A, SerialNo=YGEYG086812
 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs }
 RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=40
 BuffType=DualPortCache, BuffSize=380kB, MaxMultSect=16, MultSect=16
 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=60036480
 IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120}
 PIO modes: pio0 pio1 pio2 pio3 pio4
 DMA modes: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5
 AdvancedPM=yes: disabled (255) WriteCache=enabled
 Drive Supports : ATA/ATAPI-5 T13 1321D revision 1 : ATA-2 ATA-3 ATA-4 ATA-5

Вопрос следующий: из моего винта что-то еще можно выжать дополнительно
или достигнутые настройки оптимальны по производительности? Субъективно
мне иногда кажется, что винт работает чрезвычайно медленно при
swapping'е.
