Tried hdparm after a restart and it looks like this:


Code:
--------------------
    /dev/hda:

  multcount    =  0 (off)

  IO_support   =  0 (default 16-bit)

  unmaskirq    =  0 (off)

  using_dma    =  1 (on)

  keepsettings =  0 (off)

  readonly     =  0 (off)

  readahead    = 256 (on)

  geometry     = 16383/255/63, sectors = 156301488, start = 0

  
--------------------




So, I tried: 
Code:
--------------------
     hdparm -m16 -c1 -d1 /dev/hda
--------------------
 to restore your config and rerun 
Code:
--------------------
     hdparm -tT /dev/hda
--------------------
 and ... 
Code:
--------------------
    /dev/hda:

  Timing cached reads:   1396 MB in  2.00 seconds = 696.37 MB/sec

  Timing buffered disk reads:   30 MB in  3.34 seconds =   8.99 MB/sec

  
--------------------




That meas ... worse. Ideeas ?
