====Reduce writes: tmpfs for logging and /tmp====
You will lose files in tmpfs after reboot! Use remote syslog for important logs if you log to tmpfs.
==/etc/fstab==
tmpfs /var/log tmpfs defaults,size=256m 0 0
tmpfs /tmp tmpfs defaults,size=64m 0 0
==Large commit interval==
You can change the ext4 journal commit interval to reduce writes.
Quote: [[https://www.kernel.org/doc/Documentation/filesystems/ext4.txt]]
commit=nrsec (*) Ext4 can be told to sync all its data and metadata
every 'nrsec' seconds. The default value is 5 seconds.
This means that if you lose your power, you will lose
as much as the latest 5 seconds of work (your
filesystem will not be damaged though, thanks to the
journaling). This default value (or any low value)
will hurt performance, but it's good for data-safety.
Setting it to 0 will have the same effect as leaving
it at the default (5 seconds).
Setting it to very large values will improve
performance.
Edit **/etc/fstab** and add a commit= key value pair.
