 |
|
Bonjour,
J'ai un probleme lors d'une forte charge sur mon disque dure en AHCI
lors d'un --sync (sur ma partoche xfs), il met 15 minutes, et la mise a jour du cache (le pourcentage quoi ) est vraiment tres lent pour pas beaucoup de fichiers pourtant...
je precise que dans les memes conditions ( sans ahci ) j ai un autre laptop qui tourne au poil... en 1 minute sans saturation...
je pense que le probleme vient de l'AHCI... y a des choses a regler ?
voila mon test de disque dure ( qui veut pas dire grand chose mais bon ca confirme que ca a l air correct ):

/dev/sda:
Timing cached reads: 2140 MB in 2.00 seconds = 1070.76 MB/sec
Timing buffered disk reads: 130 MB in 3.02 seconds = 43.06 MB/sec

Faudrait voir si ton ICH8 c'est un ICH8 tout court ou un ICH8M/ICH8M-E/ICH8R.
http://www.intel.com/support/chipsets/imst/sb/CS-012304.htm
Faut que je regarde ça aussi d'ailleurs puisque je tourne sur du ICH5.
edit : ça doit être un 8 tout court, chez mon lspci me spécifie bien le -R : | Quote: | # lspci

edit bis : après, je dis pas que virer le support de l'AHCI dans le noyau résolve le problème... |
