linux maxing CPU on quality hardware
Hello folks;
This may be a topic covered before but I haven't found a close enough parallel. Online searches have not provided enough. My %CPU is running slow despite a high quality motherboard and plenty of ram. Both websites and offline programs take several seconds for typed words to propogate. Here is what the system looks like: Quad core Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor 16Gb ram with 7Gb swap drive running Linux Mint (this slowdown was also happening with the previous distro which was Deepin Linux) on an SSD. Running 'Top' shows 12% CPU, 83 id, and 0.0 wa If there is any information here that is needed, I'm happy to provide |
Mint should have a gui performance monitor that may offer more clues.

Does the preinstalled System Monitor give you any clues? It should give you a graph of all four cpu's, memory/swap usage, and the network usage. You can also switch to the Proccesses tab and see which programs are taking up resources.
Your GPU could also be a factor. I've never had a problem with AMD graphics cards but I have run into NVidea stuff that didn't play very nice with any linux distro. |
Using code tags around your paste, please provide input/output from inxi -CGSayz and pastebinit /var/log/Xorg.0.log here.

I meant to post this immediately. Here is what top looks like with only one LibreOffice document and five tabs open on Firefox

Thank you in advance everyone for your input :-) |
What about the data requested in post #4 ?. - posts crossed in flight.
There is a lot of junk on the web these days - expecting everybody to have equipment that can handle it. Have a read of this diagnostic page. |

Your problem is your computer has two GPU, and you only have a driver installed for the low power intel one.
If you enabled proprietary drivers during installation, then a `sudo ubuntu-drivers install` will probably fix this... |

I went here where the site suggests that Linux Mint users install nvidia-driver-440 the code returned from the ppa Code:
sudo add-apt-repository ppa:graphics-drivers/ppa Code:
## Current Status Code:
## WARNINGS: I also checked the linux mint GUI (enclosed is a screenshot) which does show the old Nvidia 390 driver but doesn't have an option for the 430/440 So in terminal I just did: sudo apt install nvidia-driver-450 Will respond again after update |
After installing Nvidia 450, this shows up in terminal

Try disabling javascript in FF, just to see what happens. I daresay CPU will go closer to 10%. But alas, sometimes even pure CSS can make your browser really hot and bothered. In a nutshell, it depends a lot on those 5 tabs. |
