Manjaro is slow and lagging sometimes

My system is slow and lagging sometimes.
Lagging happens when I use chrome or firefox, vs code or webstorm, have multiple http servers running or running unit tests (100+) at the same time. Also, I have docker installed and usually during work I have minimum 2 containers running. Usually when system starts lagging it kills webstorm, vs code and chrome processes.
Previously I was using ubuntu and never had problem with the same workload.

I think problem is related to GPUs and drivers but not sure.

p.s. when lagging happens, it does not seem that CPU, GPU, RAM utilization is very high (I monitor using nvtop)

my linux/arch knowledge is not advanced and idk how to approach these kind of issues. I am just a backend dev. Would appreciate if you can advice how to debug and understand what causing the issue.

Dump question, but do you have a swapfile/partition? That kinda happens when your ram is full and oomd decides to kill some applications for stability reasons.

Maybe you had a swapfile?

maybe the first line of argument after all others are extinguished is checking if manjaro vs. ubuntu have different default priorities on processes.

Having something at 0 or -20 can make all the difference. Especially when under load.

Welcome to Manjaro! :smiling_face_with_three_hearts:

  1. Please read the information behind this link. It will help you to post necessary information.

[HowTo] Provide System Information

  1. Please press the three dots below your post and then press the :pencil2:
  • If you give us information about your system, we can see what we’re talking about and make better suggestions.
  • You can do this by using inxi in a terminal or in console.
sudo inxi --admin --verbosity=7 --filter --no-host --width
  • Personally identifiable information such as serial numbers and MAC addresses are filtered out by this command
  • Presenting the information in this way allows everyone to be familiar with the format and quickly find the items they need without missing anything.
  1. Copy the output from inxi (including the command) and paste it into your post.
  • To make it more readable, add 3 backticks ``` on an extra line before and after the pasted text.

(Wisdom lies in reading :wink: )

actually idk, how to check that?

@gegham Please don’t be lazy and use copy&paste for terminal outputs. Markdown is supported here. thanks :wink:

So there is no swap as expected. If your system is running at full load, then it needs a swap. Maybe have look at systemd-swap which dynamically creates and activates swap files if needed.

@megavolt sure it’s not hard for me to do that. will start systemd-swap deamon. Thanks.

Thanks man.

@gegham So if swapping wasn’t the issue, see what @varikonniemi has already said about priorities. It could be perfectly legitimate for a process to have a high priority and make the lower priority applications wait a long time and causing it to crash.

I cannot say what the difference between Ubuntu and Manjaro is, but at least it must be the default kernel version, which is, when I remember correctly, version 5.15. You run v6.1.

Also check with iotop or iotop-c if the Input/Output performance let it crash.

There are tools like nice, renice or ionice which can adjust the priorities to your needs. Docker has its own parameters for that.

Maybe, I am not sure, it could be also a snap issue. While you can run snaps on Manjaro, it is not optimized for that. Snaps are generally optimized and tested for Ubuntu and for sure, it has always a delay when computing.

You can replace sublime-text, postman, webstorm with Flatpaks or just install it natively from the official repo or the AUR.

Get rid of the snaps - each end every one.

Then disable snap.

postman can be build from AUR using

pamac build postman-bin

sublime-text has their own repo you install from

curl -O && sudo pacman-key --add sublimehq-pub.gpg && sudo pacman-key --lsign-key 8A8F901A && rm sublimehq-pub.gpg
echo -e "\n[sublime-text]\nServer =" | sudo tee -a /etc/pacman.conf
sudo pacman -Syu sublime-text

Webstorm can be setup to run in your home

curl -O
tar -xf WebStorm-2022.3.2.tar.gz

@megavolt @linux-aarhus thanks for answers. I removed all snap apps and also removed snapd itself.
Will let you know if it solves the problem. Thanks!

with systemd snap and flatpak linux is quickly becoming a mess similar to windows, with huge effort going into working around complex configuration and problems arising from containerization

seems removing snaps solved the problem… I have been working with the same workload for couple of hours and didn’t experience any lagging. Thank you all!
