Hi,
I am hoping to get some help with my Ubuntu 20.04.2 LTS system. Takes me 5+ seconds just to enter commands, switch between apps, etc.
Try checking your hard disk's health with smartctl (package smartmontools). Try replacing the hard disk's SATA cable.
Because I am terrible at reading comprehension. Have you ruled out the usual suspects? - How much RAM as you using? free -h will help check that out? - Are you swapping? - Are you using up too much CPU bandwidth? I prefer using htop to get an ongoing view, but you could get those details from top. (Note - if you have a multicore system like most of us do today, you will see CPU consumption of more than 100%. As long as it is less than x*100 where x is the number of CPUs, you should be "fine". To know the number of CPUs, "lscpu" is a helpful command.) - Are you having some CPUs getting oversubscribed. htop is more useful in seeing this. If you see some CPUs running at 100% and others at something lower, that might be something to investigate. Dhaval
