now I am back to MX Linux again because I was a bit annoyed with Arch (Artix), AUR is nice and all for up to date stuff but it made the system unstable, crashes in applications etc…. another iteration of openzfs and still no error, but I’ll keep that in mind, thanks 👍🏻

Is it normal 4.5G memory usage?

from my experience…..it depends on the application you are using and also the windows manager. if not many applications running, it will be reduced

that is high. me 3x the #of pkgs 1/3 ram use

8mr 2022-09-20 04:54:30

i have 651+ pkgs n using i3wm. at the moment with many applications running and 2 browsers opened with about 15 tabs, my ram usabe is 5.4G. Thats normal for me. it goes up n down

Before came to freebsd I was use suckless dwm. Because still not know everything in bsd or let us said I dont know how manage the process, like mount drive or packaging … Etc. In suckless, i can reduce ram usage to 150MB to 200MB.

Thanks 🙏,

I bet most of it is buffers and cache. Do you use zfs?

svartj 2022-09-20 12:17:19

ZFS doesn’t use much memory unless you enable deduplication (which you should not)

krond 2022-09-20 12:19:00

Any system should excel at using all of your memory to speedup what you are doing.

☝️This basically.

It does from 1/3 to 1/2 IIRC if you don’t set vfs.zfs.arc_max

JayOK 2022-09-20 12:21:28

That’s the maximum it is allowed to use, not what it actually uses all the time

OP didn’t write how long the system is up and how busy it is

svartj 2022-09-20 12:26:28

Uptime is 21 mins 🙂

zfs uses quite a lot as ARC (cache), up to 50%

rob2g2 2022-09-20 12:32:13

even more … standard is total RAM minus 1GB

My Arch Linux right now (XFCE, ZFS) uses 640M
OS is different but OpenZFS codebase is the same
Cannot log on my FreeBSD instance rn but RAM usage is low there too (webserver, 12.2)

rob2g2 2022-09-20 12:43:10

yes, does not mean it eats your ram immediately. also dependent on the size of your storage pools

krond 2022-09-20 13:08:53

Hehe, define busy:
Memory: 6264M Active, 108M Inact, 2948M Wired, 80M Cache, 691M Buf, 4264M Free
Swap: 64G Total, 14G Used, 50G Free, 22% Inuse, 10M In, 8932K Out
This is just www/firefox build, 4G free RAM is due to some processes using that much RAM recently exited freeing it to the system, otherwise whole RAM would be used for cache/tmpfs.

rob2g2 2022-09-20 13:12:01

modern browsers are horrible

rob2g2 2022-09-20 13:14:08

the whole web is broken

krond 2022-09-20 13:23:01

Nah, Firefox itself is fine, but having too many cores means any parallel build will vacuum all your RAM in no time.

krond 2022-09-20 13:25:19

One compiler instance can eat 2Gb easily, which is already more then Firefox is using with all my hundred tabs.

Neville Goddard 2022-09-20 13:32:09

It takes more time to set up. Also driver support is not so good
