Slow-downs while unpacking updated packages

I applied the actual Stable Branch update:

[Stable Update] 2021-05-19 - Kernels, Nvidia, KDE Frameworks, Plasma, Systemd, LibreOffice, KDE Gear Mobile, FF, TB

I booted Manjaro USB and I executed the above (quoted) commands, and…
It took 5 minutes to do everything! No slowdowns at all!

So… Something is wrong on my system.
No hardware failures.

@linux-aarhus and also @Keruskerfuerst :
what do you think about?
