Fedora Workstation 44 exhibited unexpectedly slow performance on Framework Laptop 13 Pro hardware with Intel Core Ultra Series 3 processors, traced to the Tuned-PPD daemon, with a fix expected in a new Linux kernel.
Engineers deploying Fedora on Intel Core Ultra hardware may encounter significant performance degradation due to Tuned-PPD, which handles power and performance tuning. A kernel-level fix means the regression should resolve without manual intervention, but until then, affected systems may underperform relative to other distributions.

Fedora Workstation 44 showed unexpectedly slow performance on Framework Laptop 13 Pro with Intel Core Ultra Series 3 "Panther Lake" processors during multi-distribution benchmarking.
The performance loss was traced to Fedora 44's use of Tuned-PPD rather than a hardware or distribution-agnostic issue.
A new Linux kernel version should fix the Tuned-PPD regression, though the headline's "should" indicates the fix is anticipated rather than confirmed.
