screenshot – How to make system fast

enter image description here

I used to work on my laptop by opening chromium 3 tabs , firefox 1 tab(to run micrsoft teams) and two notepads. I have 2gb ram, dual core processor. Do above tasks makes my laptop slow? Whenever I navigate browsers by clicking Alt+tab Windows opening speed slows down. Pls suggest ideas to speed up.

I have asked above question . You asked to do below:

Edit your question and show me free -h and swapon -s and sysctl vm.swappiness and cat /etc/fstab. Start comments to me with @heynnema or I’ll miss them. – heynnema May 29 at 17:36
