They support DMA just fine.... |

...and you are getting DMA transfers. Without DMA the buffered disk |
| 15 |
read speed would be more like 3-4 MB/sec. |
| 16 |
|
| 17 |
This is not the problem. |
| 18 |
|
| 19 |
BTW, the reason hdparm doesn't show a dma mode, and the reason that |
| 20 |
most of the other hdparm options don't work with your drive, is |
| 21 |
because hdparm is meant to deal with IDE/PATA disk drives, not SATA. |
| 22 |
There really is no additional configuration that you need to do for |
| 23 |
SATA performance. |
| 24 |
|
| 25 |
AFAICT, you still haven't told us how much RAM you have, or posted |
| 26 |
your emerge --info. |

I have a single 512mb (512x1) ram. I read out that ccache would be a better idea to enchance the performance. Anbody tried that ? |
| 34 |
one more thing, i am unable to find a xorg.conf in "/etc/X11/"...where it is ? I google about that but didn't help. |
| 35 |
|
| 36 |
it's weird but true that this time (with new kernel) performance is better than before and no more emerge problems but sometimes X takes too much cpu for few secs. |
