I was suspecting that after the last communications there were some 
changes on your side, because I rebooted the VM maybe two or three times 
[1] and noticed not seeing the slow down as I was used to. I also had 
the impression that some of my other pain point improved a bit.

At this moment Debian is in freeze [2] in preparation for the release of 
Debian bookworm, hence it's rather dull on the CI side. That makes 
interpreting the Munin graphs a bit difficult. In the mean time I have 
also upgraded the VM to run Debian bookworm (around 2023-03-14), maybe 
that also make a difference.

I propose we wait with further investigations until after the bookworm 
release. Once our CI hosts are loaded normally again I think we're in a 
better position to judge real performance. Having said that, I'm happy 
to schedule and/or arrange access to an LXC container on our host for 
investigations already before that time if you want to poke around.
