[ltp] tuning with hdparm

[Konstantin Filtschew]

hi,

tried it, increase of 1 MB

before:

/dev/hda:
 Timing buffer-cache reads:   1412 MB in  2.01 seconds = 701.55 MB/sec
 Timing buffered disk reads:   78 MB in  3.00 seconds =  26.00 MB/sec


after:

/dev/hda:
 Timing buffer-cache reads:   1500 MB in  2.00 seconds = 749.36 MB/sec
 Timing buffered disk reads:   82 MB in  3.00 seconds =  27.32 MB/sec

Goz a T40 with a Fujitsu 80GB 4200rpm.

I think it's okay :)

Greetz

Konstantin
