SystemD - ejc - 06-12-2019

Hello, I use an Asus eeebox 1501b with 2 go ram and i notice that the unity gets warm quickly after boot and stays so.
Is there anything I can fix here:
The disk is 5400 rpm

Memory Usage: 1330/1993MB (66.73%)
Disk Usage: 12/293GB (5%)
with just the default pdf reader open and firefox

Hi [member=9318]ejc[/member]  First of all, your post's title "SystemD" tells nothing about what you want since then you pasted some system statistics and asked "what can I fix here" so if I may ask, what is it exactly you're looking to fix? If I understand correctly, it seems to me you're asking for help/guidance on how to improve memory management, is that correct? And there might be a number of answrs for that question, in any case, since your post asks for SystemD I think you should read here https://www.linuxliteos.com/forums/installing-software/systemd-linux-lite-3-0/msg23516/#msg23516 try some of the commands like
Code:
systemd-analyze blame
as well as the rest of them, analize its output, search on google on how to read them so you know what they're telling you. 

Hope this helps! Smile

Hello
My goal was to reduce the disk memory so that it does not get warm so quickly.

Hi,

Maybe deactivating the swap would help (i.e. forcing Linux to use RAM and less HDD usage).
I have never tried it and maybe it's a bad idea, Linux Mentors could confirm, but... Smile

Coming from the Widnows world I would sometimes deactivated swap (pagefile.sys) to "force" Widnows to use RAM (idea came with first SSD generation a few years back).
Some stupid Widnows programs "NEED" the swap though, so I had to install a RAMDisk program which makes a virtual harddisk in RAM and put the Windows Swap there (I put it at 1024MB).
Yes, I know this defeated the whole purpose of a swap Wink but never had problems "then" and probably saved a few years usage on that old-school SSD.
Note : Was on W7 and this trick stopped working in W10. I didn't check if possible anymore.

Warning  / disclaimer or whatever Wink : Maybe Linux also "needs" the swap so, I don't know if this will prevent the OS from booting. Try on unimportant machine, virtual machine first. If reallly stuck with one PC, tell me I'll try this on the week-end.

"reduce disk memory" Don't you mean disk usage? Type this in a terminal and report back the output
Code:
cat /proc/sys/vm/swappiness
From what I see, your main issue seems to be RAM, your first post shows this
Quote:Memory Usage: 1330/1993MB (66.73%)
while your disk usage is reported
Quote:Disk Usage: 12/293GB (5%)
so maybe what you need is improve your memory usage not your disk's.
