I want to speed up my ubuntu install a bit. I was using a RAID1 setup for the whole system (separate md for /home and /). Now (thanks to http://www.webdesignblog.asia/operating-systems/linux-os/resizeshrink-raid1-filesystemvolumepartition-and-setup-a-lvm-on-the-free-disk-space-created/ ) i resized my /home partition to make it smaller and build a RAID0 partition of 200GB. Most use of my desktop is browsing in many tabs, office & email usage.
I think about the cache directories of the browser (chrome, firefox, opera), cache or imap storage of thunderbird. The thumbnails cache of nautilius? What else?
Which directories should i move (link) to the faster storage?
Maybe some parts of /var? Maybe some directories should be moved to a tmpfs in ram? (I have only 8GB of ram)
For now i moved:
.cache
.java
.macromedia
.mozilla
.opera
.thunderbird
/tmp
I know, .mozilla and .thunderbird also hold the profiles, as this is not critical (using IMAP) i decided to move em.
Some command to find out which files/directories cause the most usage of the storage? (reading/writing cycles, not size)
You can have some hint with
– Hastur – 2015-01-28T00:08:45.820ls -lrtd */ .*/
in the path you want to check... e.g. which of the last directory of yourhome
is the last modified; maybe you can start reading here about the swap partition, and consider the/tmp
directory...
