Like someone else mentioned, you can switch the sched on the fly, and |
| 18 |
quite easily. From what I have seen myself: |

|

Anticipatory seems to be, at times, faster than deadline, but not by |
| 21 |
much. It tries to predict what will be needed next, where as deadline |
| 22 |
makes reads/writes based on which will be the fastest (recomended for |
| 23 |
databases and such iirc). |

In my experiance, CFQ has always been the slowest. It gives everything |
| 26 |
even time, and seems to cause alot more head movement than the other |
| 27 |
two, which is a pain. |
| 28 |
|
| 29 |
Best bet is to compile them all in, and switch them out to see what |
| 30 |
works best. For me that seems to be deadline (btw, I am running a |
| 31 |
desktop), but testing would be the best thing. |
