I have set the blkdev readahead (see command below), however on reboot it gets reset back to 256. How do I have it so that it is automatically set even after reboot or what is the best way to make this setting permanent? Please give specific detailed answer.
sudo blockdev --setra 2048 /dev/sdc1
Add the command you noted above to
/etc/rc.local
, and that will be run on each boot.
