I haden't noticed it before you mentioned it, so i tested it on my NAS over a wired connection. I also get a nice speed boost, even though it is not as big as the one you got, went from around 60 mib/s to 75 mib/s, which is a really nice boost!
Something i noticed yesterday, was that when i run: systemctl list-unit-files --state=enabled --no-pager
i used to get 12 services + fstrim timer, which is a pretty low number i think, compared to other Linux distro's (on my raspberry pi i have 34 services).After the update i get 4 service + fstrim timer. No idea why there is this big drop, after the new systemd update...
