 Posted: Mon Aug 18, 2008 6:00 am Post subject: [gnome] tout est lent (DMA, libATA) [résolu] |
 |
|
Salut,
J'ai decidé de ré-éssayer gnome apres environ 2 ans passé sous KDE, je fais donc ça sur une installation neuve de gentoo.
Le problème est que c'est excessivement lent, particulierement au niveau du lancement des apps du genre firefox (qui n'est pas un modèle de rapidité d'après ce que j'ai pu lire :/), open office, même le terminal de gnome, bref, tout est lent, mais uniquement sur le lancement initial d'un programme après un reboot.
Les recherches que j'ai éfféctués m'ont menées à 2 pistes : le fichier hosts et la DMA.
Pour le fichier hosts ... :
| Code: |
#gedit /etc/hosts :
#/etc/hosts: Local Host Database
#
# This file describes a number of aliases-to-address mappings for the for
# local hosts that share this file.
#
# In the presence of the domain name service or NIS, this file may not be
# consulted at all; see /etc/host.conf for the resolution order.
#
# IPv4 and IPv6 localhost aliases
127.0.0.1 localhost MyTux
::1 localhost
#
# Imaginary network.
#10.0.0.2 myname
#10.0.0.3 myfriend
#
# According to RFC 1918, you can use the following IP networks for private
# nets which will never be connected to the Internet:
#
# 10.0.0.0 - 10.255.255.255
# 172.16.0.0 - 172.31.255.255
# 192.168.0.0 - 192.168.255.255
#
# In case you want to be able to connect directly to the Internet (i.e. not
# behind a NAT, ADSL router, etc...), you need real official assigned
# numbers. Do not try to invent your own network numbers but instead get one
# from your network provider (if any) or from your regional registry (ARIN,
# APNIC, LACNIC, RIPE NCC, or AfriNIC.)
# |
(tiens sur le coup je m'apperçois que gedit aussi tarde à s'ouvrir :S)
Il semble coller avec le hostname.conf :
| Code: |
gedit /etc/conf.d/hostname
# /etc/conf.d/hostname
# Set to the hostname of this machine
HOSTNAME="MyTux"
|
Je pense donc que ça ne vient pas de là.
Puis pour la DMA
| Code: |
hdparm -d 1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
|
Elle n'a pas l'air de vouloir marcher, j'ai pas spécialement cherché de ce coté car je ne pense pas que cela vienne de là, mais du coup je me retrouve à cours d'idée. Quelqu'un à quelque chose à proposer ? A part emerge kde-meta ?

Salut,
| Quote: | gedit /etc/conf.d/hostname.conf
# /etc/conf.d/hostname |
Sur mon système je n'ai pas de hostname.conf, mais bien un fichier hostname.
A partir de là, si l'hostname n'est pas défini, çà peut peut-être mener à ce genre de problème. |

Erreur de ma part en recopiant la commande, ce que j'ai posté plus haut est bien /etc/conf.d/hostname .
Désolé :S |

Bon déjà ton fichier /etc/hosts n'est pas configuré correctement, ce qui poses régulièrement des problèmes de lenteur sous Gnome...
Ça devrait être qqch du genre | Code: |
127.0.0.1 MyTux.homenetwork MyTux localhost
::1 MyTux.homenetwork MyTux localhost
|
Jettes un oeil à la documentation pour voir comment faire. |

As-tu testé la vitesse de ton disque dur ?
| Code: |
# hdparm -Tt /dev/hda

J'ai réédité mon /etc/hosts :
| Code: |
# /etc/hosts: Local Host Database
#
# This file describes a number of aliases-to-address mappings for the for
# local hosts that share this file.
#
# In the presence of the domain name service or NIS, this file may not be
# consulted at all; see /etc/host.conf for the resolution order.
#
# IPv4 and IPv6 localhost aliases
127.0.0.1 MyTux.homenetwork MyTux localhost
::1 MyTux.homenetwork MyTux localhost
|
Rien n'y fait :S
Ensuite du coté de la DMA :
| Code: |
hdparm -tT /dev/hda
/dev/hda:
Timing cached reads: 1070 MB in 2.00 seconds = 534.87 MB/sec
Timing buffered disk reads: 8 MB in 3.35 seconds = 2.39 MB/sec
|
Après j'ai pas vraiment d'idée sur la vitesse de lecture, comme j'ai rien pour comparer je peut pas dire si c'est correct ou pas :/ |

Pour la théorie, il est pas bon ton fichier hosts. Devrait ressembler plus à ca:
| Code: | 127.0.0.1 localhost
::1 localhost
<ton @ipv4 princiale> tonhostname.tondomaine tonhostname
<ton @ipv6 princiale> tonhostname.tondomaine tonhostname |
mais ca devrait pas changer grand chose.
Pour ton hdparm "buffered reads"... pas joli 
| Code: | saidar ~ # hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 1484 MB in 2.00 seconds = 741.89 MB/sec
Timing buffered disk reads: 188 MB in 3.03 seconds = 62.14 MB/sec |
(disque SATA qu'a qd même 2-3 ans, donc pas la pointe de la techno)
Dans mon souvenir, il fallait faire bien attention à sélectionner son chipset
dans la config du noyau et QUE son chipset, pas le truc "generique". Mais
c'est un peu vieux, je suis plus très sûr. |

C'est le controleur ATA/IDE qu'il faut. Si tu es pas sûr, envoie-nous le résultat de /usr/sbin/slpci.
(emere pciutils si tu l'as pas.) |

| Et tente de passer en libata en même temps, ça sera ça de fait, la vieille pile IDE est à peine maintenue et va disparaitre, et elle a ses problèmes. ;p |

Et si tu veux être certain de ton coup, envoie nous le résultat de cette commande :

J'irais zyeuter la libATA dès que je m'en serais sorti avec cette DMA 
Voila le lspci :
| Code: |
lspci -v

Heu justement si on te conseille de passer en libata, c'est pour corriger le problème de DMA  |

Je m'apperçoit qu'il manque des options dans le kernel (j'utilise les dernières gentoo-sources : Linux Kernel v2.6.25-gentoo-r7 en 64 bits) notament :
Device Drivers -> ATA/ATAPI/MFM/RLL support -> Generic PCI bus-master DMA support
Cela n'apparait tout simplement pas, comment ça se fait ? |

Oh, pas bon ca "unknown device". Tu peux nous donner le lspci -vn pour avoir le device id complet?
C'est quoi ta bécane? (Un portable tout neuf?)
Sinon, ben comme tout le monde semble l'indiquer, faudrait essayer avec libata, c'est plus moderne
et donc plus mieux forcément - surtout avec un contrôleur manifestement relativement moderne.

Salut, pour ton unknown device, as-tu essayé ceci :
| Code: |
# update-pciids
# lspci

Ensuite la libATA j'ai éssayé, seulement en desactivant le support ATA/ATAPI/MFM/RLL comme c'est conseillé, je n'arrive tout simplement plus a demarrer correctement, j'ai une erreur pendant le boot comme quoi ma partition root est introuvable.
J'ai dut mal m'y prendre il faut qu je rééssaye. |

C'est quoi l'erreur exacte ?
A priori, 2 pistes :
- tu n'as pas compilé le support de ton contrôleur en dur
- tu n'as pas adapté ton grub.conf pour tenir compte du fait que les disques /dev/hd* deviennent /dev/sd* avec la libata |

Ah ça a changé, j'ai réésayé sur un kernel cobaye, j'ai compilé le support en dur et adapté le grub.conf.
Maintenant tout se passe bien jusqu'a l'etape du boot ou le systeme de fichier de la partition root est vérifé, voila ce que j'obtiens :
Checking root filesystem ...
fsck.ext3: No such file or directory while trying to open /dev/hda4
/dev/hda4: The superblock coul'dn't be read or doesn't describe a correct ext2 filesystem
J'ai zappé une modif dans le fstab ? Il me semble pourtant qu'il n'y en a pas à effectuer :S |

Bien sûr qu'il faut remplacer hd* par sd* partout où ça se présente, donc aussi dans le fstab !
Il _te semble_ ou tu es _sûr_ d'avoir bien tout adapté ? (la nuance est de taille ! )
Eventuellement, fais voir ton fstab ... |

Ca marche <3
J'ai adapté le fstab et la libATA a résolue tout mes problèmes, la vitesse de lecture a sensiblement augmenté :
| Code: |
hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 1830 MB in 2.00 seconds = 915.78 MB/sec
Timing buffered disk reads: 146 MB in 3.03 seconds = 48.15 MB/sec
-----
hdparm -i /dev/sda
/dev/sda:
Model=Hitachi HTS542520K9A300 , FwRev=BBDOC32P, SerialNo=071116BB0D00WHG2K2MC
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4
BuffType=DualPortCache, BuffSize=7229kB, MaxMultSect=16, MultSect=?16?
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=390721968
IORDY=on/off, tPIO={min:120,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 *udma6
AdvancedPM=yes: mode=0x80 (128) WriteCache=enabled
Drive conforms to: unknown: ATA/ATAPI-2,3,4,5,6,7
* signifies the current active mode

Tout est clean donc, et le system est autrement plus fluide.
Merci à tous d'avoir pris la peine de répondre, et surtout d'avoir été aussi patients  .
Je marque le sujet comme résolu |
