# Add blockdev command to set readahead in /etc/rc.local
# Set readahead for mongodb storage device
blockdev --setra 32 /dev/<mounted device>

Future Further Improvements: 
- It is best to use RAID 1+0 with 4 SSDs for MongoDB server storage
- Further tuning with readahead from 16 to 32 sectors of 512 bytes (16 KBs)
