In an attempt to make this thread of more use to others, I'll go through
steps of optimisation, one at a time. (This will also help me not break
my machine in one big optimisation "fix" :-)
Let us start with hdparm. Any suggestions for improvement welcomed,
short of selling the drive and getting a faster one.
Here are the bits of information I have:
hdparm /dev/hda:
/dev/hda:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 38760/16/63, sectors = 39070080, start = 0
Three runs of hdparm -tT:
/dev/hda:
Timing buffer-cache reads: 344 MB in 2.00 seconds = 171.77 MB/sec
Timing buffered disk reads: 74 MB in 3.01 seconds = 24.56 MB/sec
/dev/hda:
Timing buffer-cache reads: 344 MB in 2.01 seconds = 170.83 MB/sec
Timing buffered disk reads: 76 MB in 3.01 seconds = 25.25 MB/sec
/dev/hda:
Timing buffer-cache reads: 344 MB in 2.02 seconds = 170.24 MB/sec
Timing buffered disk reads: 76 MB in 3.00 seconds = 25.33 MB/sec
hdparm -i:
/dev/hda:
Model=IC25N020ATCS05-0, FwRev=CS2OA61A, SerialNo=CLP201F2G1XBHA
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4
BuffType=DualPortCache, BuffSize=7898kB, MaxMultSect=16, MultSect=16
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=39070080
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
UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5
AdvancedPM=yes: mode=0x80 (128) WriteCache=enabled
Drive conforms to: ATA/ATAPI-5 T13 1321D revision 3:
* signifies the current active mode
/etc/hdparm.conf
/dev/hda {
mult_sect_io = 16
