What filesystem are you using? I've seen this kind of behavior with |
| 9 |
XFS, and the anticipatory scheduler, and solved it with the following |
| 10 |
in my /etc/conf.d/local.start: |
| 11 |
|
| 12 |
test -f /sys/block/sda/queue/iosched/antic_expire && \ |
| 13 |
echo 0 >/sys/block/sda/queue/iosched/antic_expire |
| 14 |
test -f /proc/sys/vm/laptop_mode && echo 0 >/proc/sys/vm/laptop_mode |
| 15 |
test -f /proc/sys/fs/xfs/xfssyncd_centisecs && \ |
| 16 |
echo 500 > /proc/sys/fs/xfs/xfssyncd_centisecs |
| 17 |
|
| 18 |
You might also play with some of the other settings in |
| 19 |
/proc/sys/fs/xfs and see what works for you. |

Of course, if you are using a different filesystem or different |
| 22 |
scheduler, it might help to know that. |
