Computer slows down

Question

I am running latest Ubuntu having upgraded (twice now I think). When I boot up, my computer is using 600Mb of memory. I then use 3 instances of Chrome with multiple tabs, Atom and VS Code and run gulp in the terminal.

After a day, my computer is often much slower. If I close everything I am still using 3Gb of an 8Gb machine, and I may have used a very little of the swap partition. There is a little background network connection going on. It ends up being easiest just to reboot, but that is not what I expect from Linux.

Should I be worried, should I change something?

You can try to debug the situation more with vmstat (package procps), iostat (package sysstat), iotop (package iotop). Looking for those tools in google yields many guides about finding system's bottleneck.
