I am using a brand new lenovo x1 carbon 5h generation and whenever i use a browser(chrome or firefox developer), all of my CPU cores suddenley run at more than 80%.
Just openning firefox causes my CPU to use a lot of resources.
This is from running 4 tabs in firefox developer.
I have had this issue for a long time and was normally using chrome. On chrome the issue is even worse. There i have tried:
- reinnstalling chrome
- disable harware acceleration
I have tried some similar configurations on firefox as well as this approach: http://www.omgubuntu.co.uk/2017/04/small-tweak-makes-firefox-linux-run-much-faster
Specs for mye machine:
I basically only use my machine with:
- VS code
- a couple of terminal windows
- multiple browser windows with several tabs
My machine is also linked to a dock with two external monitors
UPDATE based on comments: Closing vs code seems to improve the performance a bit, and based onther issues it might be linked to some of the extensions i have installed:
- Azure account
- Azure app service tools
- Azure cli tools
- Azure resource manager tools
- Azure functions
- Azure cosmos db
But with all these extensions disabled, firefox is still using huge amount of resources:
Running atom instead is only having a slight improvement.
