The hdparm optimizations, the CFQ scheduler and maybe low latency |
| 12 |
desktop in the kernel are the best way to make your desktop useable |
| 13 |
under heavy disk usage.These are my hdparm settings: |

/dev/hda: |

multcount = 16 (on) |
| 17 |
IO_support = 1 (32-bit) |
| 18 |
unmaskirq = 1 (on) |
| 19 |
using_dma = 1 (on) |
| 20 |
keepsettings = 0 (off) |
| 21 |
readonly = 0 (off) |
| 22 |
readahead = 256 (on) |
| 23 |
geometry = 26310/16/63, sectors = 26520480, start = 0 |

cat /sys/block/hda/queue/scheduler |

noop [cfq] |
