So bigger are better, but you shouldn't give all cards a high latency, probably only the IDE controller should have a high one. In your case other cards may have a latency of 0 (except the network card). Anyway, I don't think it won't make so much differences. > |>>can i change it after the system is running ? > |>> > |>> > |>yes, > |>To see the current scheduler on hda: > |>$ cat /sys/block/hda/queue/scheduler > |>noop [anticipatory] > ]- i'm with devfs :"( This is not devfs but sysfs. # mount none -t sysfs /sys But normally Gentoo do that for you at boot time.
