Some of my stats if they can be of help. My system is modest (4GB RAM).

I don't see any particular issue on wired memory after 8-day uptime. I
see it in Firefox memory usage.. it's outrageous. 

Here are the top -sorted by RAM- processes

Firefox has been the only reason to increase my swap space. On another chapter,
it also uses LLM :( , so really looking for an alternative. (netsurf is very nice
and lightweight, but does not support JS.

Not sure if Konform will build on NetBSD, being based on LibreWolf &
Tor..

Best,
