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 owner@owner-HP-Compaq-8000-Elite-CMT-PC:~$ free -h total used free shared buff/cache available Mem: 7.6Gi 1.9Gi 1.0Gi 103Mi 4.7Gi 5.3Gi Swap: 2.0Gi 699Mi 1.3Gi
will help check that out?
- Are you swapping? I don't know.
- Are you using up too much CPU bandwidth?
