My idle xfce using 1gb memory

Hello, first of all I am all new to arch base distro’s. I have migrated from deb to arch day before yesterday. After installing manjaro the first thing I did was open task manager then htop. Both of them showed 1.2gb of ram usage where there was no programs opened. I do not have a swap partion I use i3 8gb ram 1gb vram. I previously use to get 300/350 mb memory usage on deb but it is showing too high in manjaro. Please help.

your post is confusing, are you using xfce or i3.
if your checking htop, click the memory section, it’ll line up by use.

Hi @prego.softs, and welcome!

2 things about your post:

  • Just because you don’t see it yourself, doesn’t mean there’s nothing running. Your file indexer (I don’t know if Xfce has something like that) will, especially, be taking up much resources just after installation. There are many other things.
  • RAM (memory) not used, is wasted and pointless. It would have, actually, been a much bigger problem if it tried to use 16GB of your 8GB RAM.

I have 16GB and I just checked, my RAM usage is ~4.7G.

Also, having things in RAM makes your system more snappy, since RAM is much faster than a HDD or SSD.

So relax, there’s nothing wrong, and remember: RAM not used, is RAM wasted.

Can you post the output of top here ?

OP probably meant Intel i3 processor.

yeah, that makes since. was just to tired to realize.
i have xfce4 running on a rpi400, don’t really notice the 4gb ram growing on my setup.
with just firefox open to this forum i’m ±800mb for usage & it drops -300 when i close firefox.

but you know what they say, “unused ram, is wasted ram” linux caches for faster access the next time the app is open.

i just let it do it’s thing, unless it’s causing problems, i see nothing to worry about.

The article clears a lot of stuff I didnt even know about linux as I am a newbie thank you. Still I will post the tasks result which might give everyone here a bit of light into whats happening, I will be convinced once the members over here give an “ok” signal after seeing the screenshot

Can you post the output of top here ?

like htop, top is a command ran in a terminal
It displays a nice summary of the most important things
memory usage included
it looks like this

You should start your computer and login without starting programs like Firefox.
And then use top on console.

I have a computer with XFCE as GUI.
When I login (one file manager and one terminal open), I have a memory consumption of 468 MB.

Well a funny thing happened, first when I was starting my computer and seeing task manager or htop it was showing 1.2gb but now suddenly it came down to 650mb which is acceptable. And I have seen 650mb usage in some youtube channel when I was watching manjaro review. Anyways a big THANK YOU ALL for taking time out for a noobie like me. I guess this is somewhat not even a problem.
