Ubuntu 23.04 Laptop Performance Mixed Against Ubuntu 22.10
When it came to CPU workloads, the Tigerlake and AMD Rembrandt laptops saw similar performance to Ubuntu 22.10 in many workloads... But right off the bat with the Core i7 1280P Alder Lake laptop there was noticeable performance regressions.
The Alder Lake laptop performance regressing on Ubuntu 23.04 carried into other CPU/system workloads too....
Without any other changes made to the laptop between the Ubuntu 22.10 and 23.04 installs, Ubuntu 23.04 was performing much worse than Ubuntu 22.10. There weren't any Intel P-State governor changes or the like from 22.10 to 23.04 as an initial thought...
For most workloads, the Core i7 1280P laptop was exhibiting much worse performance with Ubuntu 23.04 than 22.10.
