So, do both have the same top frequency? Yes, it's a: 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz > 4. And powerd(8) mentions a -v option: "Verbose mode.

Yes, that's where I noticed the "gradually run slower and slower"... Initially I thought it was some kind of thermal throttling, but leaving the computer idle overnight did not lead to automatic recovery, whereas reboots and as far as I can tell, restarting powerd does. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
