Sweet!
Now its time to sudo nano /etc/mkinitcpio.conf !
Then find the line starting by MODULES=" , and remove everything between the quotation marks and add ahci sd_mod ext4 in between of the quotation mark.
Then find the line starting with BINARIES=" and clear everything (or add fsck fsck.ext4 if you want to check the disk quickly at startup)
Now find the line starting with HOOKS=" and remove everything except base .
After that go completely to the bottom, and add COMPRESSION="cat"
Ctrl+S to save, Ctrl+X to leave.
You may then execute sudo mkinitcpio -P , sudo update-grub and reboot!
It should be 10% faster (results may vary)!
