Re: High CPU Usage on Fresh Install
Reply #2 –
CIFS not mounted.
Found out what the primary issue was: An issue with my PCIe was triggering an incredible amount of logs, which filled up the disk and consumed my CPU greatly. Disabled the logs (as a band-aid) and my CPU idles at 5-10% now. However, I am still having some slight CPU performance issues while running programs, so included below is the output of top:
