echo "noop" > /sys/block/cciss\!c0d0/queue/scheduler 
blockdev --setra 65536 /dev/cciss/c0d0
echo 512 > /sys/block/cciss\!c0d0/queue/nr_requests
echo 2048 > /sys/block/cciss\!c0d0/queue/read_ahead_kb
 Timing cached reads:   6114 MB in  2.00 seconds = 3058.43 MB/sec
 Timing buffered disk reads:  1090 MB in  3.00 seconds = 362.88 MB/sec

I love learning new things and trying out the latest technology.
