What I/O scheduler are you using? Did you try to experiment with the |
| 13 |
deadline or the cfq I/O schedulers? |
| 14 |
If you have them enabled in your kernel config, read |
| 15 |
Documentation/block/switching-sched.txt and see if things get better |
| 16 |
after changing the I/O scheduler for your hard disk. |
| 17 |
Of course, your problem might be caused by something else altogether. |
