I need to tweak my Dell XPS 13z SSD for maximum performance and life cycle than I read the solutions explained here, but it is for 11.10 and my fstab is different.

For now my fstab is looks like this:

    proc            /proc           proc    nodev,noexec,nosuid 0       0
# / was on /dev/sda1 during installation
UUID=abf5ce9e-bdb7-4b2f-a7bd-bbd9efa72a98 /               ext4    errors=remount-ro 0       1
# /home was on /dev/sda2 during installation
UUID=491427b2-7482-4483-b6eb-7c564b991aff /home           ext4    defaults        0       2
# swap was on /dev/sda3 during installation
#UUID=7551000d-e708-4e0f-9fd2-9f93119f63fb none            swap    sw              0       0
/dev/mapper/cryptswap1 none swap sw 0 0
tmpfs     /tmp         tmpfs      mode=1777

And my rc.local is looks like this:

echo noop > /sys/block/sda/queue/scheduler
echo deadline > /sys/block/sda/queue/scheduler
echo 1 > /sys/block/sda/queue/iosched/fifo_batch

exit 0

Do you have any suggestions, what should I do?

Regards
