I'm not sure if this will help. I explored GPIO on Debian a bit and posted
my code at https://github.com/HankB/GPIOD_Debian_Raspberry_Pi

I'll give it a try.

You would have to try it to see if it is faster for your workload. I

That matters for Linux installed directly on the M1/M2 hardware. The OP
mentioned "UTM / QEMU" so I thought he was talking about running these in a
VM. Woulldn't th

Some additional information that might be useful is that the system seems
unable to determine CPU frequencies. For example
root@up:~# cpupower frequency-info
analyzing CPU 0:
no or unknown cpufreq driver is active on this CPU
CPUs which run at the same hardware frequency: Not Available

I started installing packages I thought were likely to cause the regression
(one or two at a time) and following installation of raspi-firmware the
problem appeared.

First of all, many many thanks for making Debian work on a Raspberry Pi 4B.
I bounce back and forth between Bullseye and Bookworm on a Pi 4B and have
noticed a performance degradation with Bookworm.
TL;DR
Install (current) Bookworm - performance good.
apt update/upgrade - performance tanks.
