Your load average is basically sky high
14:01:32 up 1 day, 22:37, 0 users, load average: 18.98, 19.33, 19.05 Cores: 8
On an 8 core machine, 100% utilization of the cpu means a load of 8. You're running at the time of the diagnostics ~19 which means that for every process running, there's another 2.5 also wanting to run but they can't as the CPU is already running full tilt.
