SUMMARY
KDE is lagging horrible on all sorts of io events. It also affects other applications.

STEPS TO REPRODUCE
1. Copy files from one drive to another (or extract an archive, ...)

OBSERVED RESULT
KDE is lagging as hell

EXPECTED RESULT
Working fine, no lag spikes

ADDITIONAL INFORMATION
I do have an NVME SSD installed, I can also see this on a lot of other devies that run KDE software. I am observing this for years, but now (I am just copying 50 GB over the network) it is really REALLY annoying.
