I have an M4 Mac mini, bought last year: when running macOS 15·x
After upgrading from macOS Tahoe 26·0·1 to 26·1, I’ve notice the occasional freeze when lots of apps are open.
And that the thing seems to over heating: far more than it did under 26·0·1.
Does Anyone know what’s happening?
Or how — bar rolling back to 26·0·1 — to solve this?

Any relationships to current issues ?
No, that's fine. That's well within the range of variability for speed tests. One could run the same test on the same machine and come back with values that are even more disparate.
Plus, the first one did have some measurable I/O activity. That would also explain a slight decrease. It isn't exact math because I/O is a shared system and hardware resource. Even a little bit of activity querying file system attributes, not even reading or writing data, will slow down the read/write speeds of other tasks.
Thank you for your expertise

Right …
A week after the issue seems to have been solved … I’m getting (mild) freezing again.
With 12 Safari windows open, one Pages file, one Finder window, and one LibreOffice spreadsheet open.
Obviously, clearing the same cache as last time will help.
But what do people think is causing this?
There have been several suggestion already put forth
What has the user ( you ) attempted from any of the 3 different suggestions ?
Well … I’m not deliberately using Pages with iCloud.
Although the files are showing up iCloud>Documents>Paul’s Documents>Unfinished Quizzes>Example files.pages …
Found that thread and for your reading purposes

OK … boiled down into plain English, Owl, what am supposed to be doing?
Has it worked for others?
I don’t think I’ve got a dongle: I just have an HDMI cable connecting the Mini to a 27” U27B3M: I have the monitor set to 2k: although it’s capable of 4k.
(The cable was new: about a year back.)
