System performance is not OK.
System performance is not OK.
Hello,
When I want to open some files together then my system hanged. For example, I'm downloading a file and played a song and launch a VM then music interrupted and system hanged for some minutes. My system is Core i7 and have 16 GB of RAM. I have enough free space too.
How can I troubleshooting it? I checked by "iotop" or "htop" commands, but not found anything odd.
Thanks.

Re: System performance is not OK.
Yes, the system "hanging" for a few minutes and then recovering matches what happens when it runs out of free RAM and has to resort to swapping to the hard disk for a period.
There are several ways to keep an eye on used RAM--I prefer to have a widget on the taskbar that shows it, updated every second. What widget is right for you depends on your desktop.

My system has enough free memory:

$ sudo free

Re: System performance is not OK.
Check logs for one. Like "journalctl -p 3". Do 2 and 1 with it too. Would also help if you gave more info about your hardware. Many ways to do it and much software for gnu/nix available for the purpose ie:inxi etc etc. Somebody might spot a problem child component or whatever else. Lastly would definitely advise lowering your swappiness to 10. Edit the /etc/sysctl.conf file and put this at the bottom.

# Lower swap to a more reasonable level
vm.swappiness=10

If a solid state drive is used try also every so often :

fstrim -v /
Re: System performance is not OK.
Some here have suggested your VM might be to blame. Regardless of which software you use for that, have you allocated RAM sensibly for it and not handed over a huge amount?
Also, does this only happen when you use a particular program (i.e. your VM) or any of them? Try to narrow it down through observation in case it's just one piece of software or combinations.
