My laptop (Dell Precision 7560, i7-11850H, Ubuntu 22.04, kernel 5.17) really felt sluggish, so I ran Passmark and to my shock the results were abysmal.
Compared to the average, single threaded was only 1769 MOps instead of 3,193 MOps. Further tests reveal that the cpu boosts to ~3.8GHz for the first test, but then falls back to 2.5 GHz for the remaining tests. On the flipside, the fans never really spin up.
What I already tried:
- Installed latest bios
- set thermal management to "ultra-performance" in bios.
- set cpu-governor to 'performance' (sudo cpupower frequency-set --governor performance)
- set Power Mode to 'performance'
Nothing resolved the issue so far. Any ideas?
