What is my Experience?
But when I was resolving another error, I stumbled onto this issue.
Currently with 460 MB of RAM usage by Chrome, my total CPU usage is well below 20%.
Though it may spike up to 30 to 50%, it never comes up to 90%.
It is when Im using the minimal of apps like Word, Notepad++, and File Explorer.
Also we have some background apps running, which do not take up much of RAM and CPU time.
Though my Memory usage is around 43%, my CPU usage shuffles between 10 to 40%.
