Defrag - then00b - 09-05-2016
How can I defrag on this OS?
Re: Defrag - Wirezfree - 09-05-2016
There are varying opinions on the need to defrag Linux in normal desktop day to day usage, and only required for heavy duty servers/databases etc...
But to Check & Defrag your root /
Code:
sudo e4defrag -c /
sudo e4defrag -v /To check & defrag /home
Code:
sudo e4defrag -c /home
sudo e4defrag -v /homeMore details on e4defrag

Got an SSD?
Forget it for your own good.

@richtea
You raise a good point, however:
1. Read/Write issues with the current(new) generation of technology removes this issue.
SSD are widely used now in data centres without issues where read/writes are many, many magnitudes greater than home users
2. Also the regular disks/spinners read/write sequentially, hence the need to keep everything aligned by defraging
SSD's work completely different, they have controllers that work with the random data placement, so defraging is less of an issue.

Hey man! Thanks! The reason I want to defrag it coz my laptop is getting slower, I don't have a lot of files. So, I'm hoping it could solve the problem.

There is just one correct answer to:

Namely: "But why?"
Now we know:

Not a lot of files, so why fragmentation in particular should be the cause of a slowdown? It is more like trying to take a pot shot at the issue.
On Linux, generally, defragging is an exercise in futility. There are just two scenarios when it might have an effect:
1. Massive databases that are continuously amended.
2. HD packed to the gills with stuff.
Having used Linux OSs for some 15 years now, I have never, ever had to defrag. Frankly, I do not think there is much dissenting opinion on that.

Agree with richtea, no point in defragging in linux, but if it gives you peace of mind then go for it.

Just my plugged nickle and to maybe add help to then00b....
Defragging was the go to for Windows for PC slowness, usually; clear temps, cache, disk clean up and defrag...
You can also use "Lite Tweaks" to clean up/maintain the system similarly to disk clean up.. Anything marked safe is a no brainer; those marked caution are more so for specific fixes for problems so be mindful when selecting.
For slowness, maybe adding a bit more info; when are you noticing the slow down.. browsing, working with "XX" application or in general = boot up etc..
Along with system specs or the output of
Code:

Re: Defrag - Valtam - 09-06-2016
Your specs aren't that bad. You'd be better off upgrading to a cheap SSD. Your hard drive is pretty low spec.
