====== Ext4 file system speedup by disabling the journal ======

Creating file system:\\
<code>
mkfs.ext4 -O ^has_journal /dev/sda1\\
tune2fs -o journal_data_writeback /dev/sda1\\
</code>

For more performance use this fstab line for mounting:\\
<code>
/dev/sda10 /opt ext4 defaults,data=writeback,noatime,nodiratime 0 0
</code>
