How to properly activate TRIM for your SSD on Linux: fstrim, lvm and
dm-crypt
http://blog.neutrino.es/2013/howto-properly-activate-trim-for-your-ssd-on-linux-fstrim-lvm-and-dmcrypt/

I have decided not to activate TRIM, because I have the LVM + LUKS
encrypted installation. I have left approximately 10% of free space on
the SSD without partitioning as Overprovisioning.

I also recommend reading this post:

>    ii) how to configure the 'swappiness'

for this you need to edit the file: /etc/sysctl.conf and add at the
end the following line

vm.swappiness=20

save and reboot
