SWAP usage running HA OS

[bcutter]

Since switching hardware from Pi 4 to Pi 5 (NVMe SSD) I noticed HA OS prefers to use almost all available SWAP space instead of using RAM (like before on the Pi 4 with a quite slow disk storage).

In general I am wondering whats the reason for this behavior. I mean there's plenty of disk space and it is quite fast, but also there's plenty of (even faster) RAM available not used at all.

During nightly backup it uses even all available SWAP space (100 % usage).

HA OS 14.2.

You can run this via developer SSH or keyboard & monitor to see what uses the SWAP. I got most of the command from here.

for file in /proc/*/status ; do awk '/VmSwap|Name/{printf $2 " " $3}END{ print ""}' $file; done | sort -k 2 -n | tail -n50 | column -t

Does this actually cause any problems? SWAP usage itself is not necessarily an issue.
