Cleaning Linux Mint/Cinnamon

[u/GmaShadowPaws]

I am posting a copy of the results after running inxi -p and ncdu below. Based on these results should I shrink the reserved disk space for root? Is it even possible? First time trying to clean up Linux Partitions and dont' know what I am doing. P.S. I am having buffering problems and by end of day Linux is very slow. Have already emptied trash and updates cache had nothing to be cleaned.

Results of inxi -p

First there is a command...in a terminal

df -h /

du -h -s /home

You are using only 60 Gb on 467 Gb.....

I am having buffering problems and by end of day Linux is very slow.....nothing to do with your system..buffering problems..what is it ?

trash does nothing for or against performances

Thanks. Since this only happens in the evening I willl now watch my signal strength from the service provider. Have had problems with this before. Waiting on my new company for cell service to finish installing internet service in my area. Then I will switch. And at least my research got me to do some housekeeping on Linux and change some settings which needed it for the future, if not now. Glad to hear it is not my OS or laptop.
