I know EXT4 is the fastest by 3y already checking test blog posts from different authors But theres also other settings that make SSD faster i found in http://www.howtogeek.com/62761/how-to-tweak-your-ssd-in-ubuntu-for-better-performance/
sudo gedit /etc/fstab add to / partition <options> noatime,nodiratime, and also if kernel is >2.6.33 also add discard, tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
sudo gedit /etc/fstab add to / partition <options> noatime, and thats it and data=writeback mounting option if you formatted the disk without journaling. Otherwise add data=ordered which sould be a good compromise between full journaling and none at all. tmpfs /tmp tmpfs nodev,nosuid,noexec,mode=1777 0 0
why only noatime? And how to know if disk is without journaling from installation? And whats faster? No Jornaling or opposite? And diff no journaling data=writeback or journaled data=ordered?
And why tmpfs /tmp differs in both arcticles and how they dffer and witch is better and why?
All of this is about SSD but can i use same settings in HDD? I want to find answer for HDD and SSD as ive made one time scripts for setting it up in my https://wiki.ubuntu.com/Kangarooo/AfterCleanInstallation
