 |
|
Hi!
I noticed that my Gentoo installation takes a very long time to boot ... my previous Suse 8.0 installation had more software and services installed and booted 2-3(!!) times faster than my gentoo now. Even when the system is up everything is slow - Konquerer takes about 10 seconds to load.
My system is a Duron 800 with 256MB Ram..
Somewhere I've read about hdparm -d so I tried this:
| Code: |
root@starbase / # hdparm -d /dev/hda
/dev/hda:
using_dma = 0 (off)
root@starbase / # hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
using_dma = 1 (on)
root@starbase / #
|
This speeds things up...but as soon as I reboot, the boot sequence takes as long as before and using_dma is back at 0. How can I make gentoo remember this?
Maybe this output helps anyone:
| Code: |
root@starbase / # hdparm -i /dev/hda
/dev/hda:
Model=ST320430A, FwRev=3.11, SerialNo=7BX06FZ3
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=0
BuffType=unknown, BuffSize=512kB, MaxMultSect=16, MultSect=16
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=40079088
IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4

root@starbase / #

Any more tips how I can speed up my Gentoo? |

You can do this by sticking your hdparm command in /etc/conf.d/local.start. For example:
| Code: |
sh-2.05a$ cat local.start | egrep -v '^#'
/usr/sbin/opengl-update nvidia
/etc/init.d/gpm start
/usr/sbin/hdparm -d1 /dev/cdroms/cdrom0
|
However, I'd look to trying to get your drive recognized as capable of DMA access without hdparm (i.e. tweaking your kernel configuration)...hdparm is a rather dangerous tool if not wielded precisely. (I learned that the hard way.  ) |

| You need to recompile your kernel with the southbridge support for your chipset, after this Gebtoo should recognize the HD automaticlly and enable DMA and all the good stuff thet make the JD work fast. |
