I'm using Kubuntu with KDE Plasma 5.3 (Just installed the system a few days ago)

Something strange is happening..The system is very, and I mean VERY laggy.

When I'm doing simple tasks like leaving chrome opened and watching something on VLC and Ktorrent is downloading in the background.

My specs:

Intel Core2Duo E7500 2.93GHZ

AMD 5570 1GB DDR3

2x 2GB Kingstone RAM

And here's a screenshot from the system monitor. Screenshot

The strange thing here is that the system resources aren't all used up.

You have a laggy system because you have a lot of swap being used. You have around 512 MB Swap Being Used. You seem to have a Standard Spinning Hard Disk which means swapping will cause your System to Go Crazy Slow.

I had the same issue with my laptop I did the below.

1) Reduce the Swappiness to 10. Use this Wiki

https://help.ubuntu.com/community/SwapFaq

2) Get rid of Swap completely. Remove the Fstab entry for SWAP.

sudo nano /etc/fstab Remove the Entry for your swap partition.

3) sudo apt-get install zram-config

Now my system swaps to RAM instead of slow Hard Disk Drive which is causing slowness.

To establish this please do the below.

1) sudo swapoff -a

See if system responsiveness Improves. If yes then your problem is swap and you may follow my answer to fix this.

Since I have experienced this first hand, I can confidently say it will work for you.
