ext4 tunnig

Post with image

Now, get ready for ext4 file system tunning for speed.

1) Change your filesystem to load in writeback mode (default is journal).

tune2fs -o journal_data_writeback /dev/sda1 (change sda1 with your hard drive partition)

2) Edit fstab to change ext4 mounting options.

nano /etc/fstab

(change nano with the text editor of your choice)

Change relatime (or whatever option is there) with:

noatime,journal_async_commit,data=writeback,barrier=0,nobh,commit=60,errors=remount-ro
