Whole system becomes slow after few hours
 

Hi,
I am a former Debian user and strong fan of Debians stability, what I don't like about it is that it takes weeks to get everything running after installation.
so I installed LMDE2 and was very surprised to see that everything is working perfectly in just few hours, really, very user friendly.
Now, few days later my problems started in regard to the stability. When I turn on the system, everything works fine and fast. After few hours of the system running (and some inactivity I guess), everything becomes very, very slow - browsers switching tabs, text editors, Start menu, just everything, and I need to restart or close all programs and reopen them. Is this info helps as well - when I have had some inactivity and the system is really slow, when I start some activity it is terrible the first minute and so, and then improves a bit, however, it is still much slower as compared to after fresh restart. I have started investigating and the only thing that came to my mind was to check the "top" processor activity, well, everything seemed to be fine, once I got Firefox running on 35%, and once I got everything below 6%. Do you have idea how to debug and solve the problem? I read it might me related to SWAP settings or something?
Thanks!

Is your RAM filled up (due to a memory leak)?

LMDE is still pretty much beta. Linux Mint itself with the XFCE desktop is stable.

I just hate Ubuntu and its constant bugs. Debian is the most stable distro I have tried in 5 years, the problem with it is that is not user friendly at all and you need to configure lots of things. Was hoping I can get its stability + user friendly IF when getting LMDE2.

Stability and user friendly? Have a look to Slackware!

What units are these, what command printed it?

You might try running `top -o %MEM` to see which programs are using so much memory.

To temporarily disable the swap partition, run `swapoff -a` as root or sudo.

Later on you can disable it from getting mounted after startup, edit and comment out the entry in /etc/fstab, if you need to.

Thanks for suggestion. I might give it a try, but I guess will first try to get things fixed here to save re-installation time.

@Emerson Well I ran the suggested command and it turns out everything from the top usages comes from chrome. Shall I try using FF instead of it or what?
I frankly do not understand why I should turn off swap... Isn't it supposed to provide more memory, exactly the opposite?

Try the reinstall I've not had the problems you're having

Chrome uses massive quantities of RAM. You may want to lower swappiness to prevent slowdown.

Thanks for all suggestions. So far I am using FF instead of Chrome and things seem to be quite fine.
@Germany_chris I guess it's a matter of hardware configuration compatibility with the distro, as lots of times it does happen one user to have some problems which other do not.
