Extremely high ressource usage - Is that normal? about linkwarden HOT 3 CLOSED

Yes that's normal. As @GoodM4ven mentioned, you can lower the ARCHIVE_TAKE_COUNT down to 1 (5 is the default).
It's basically the numbers of tabs it's opening (to archive links) behind the scenes divided by two, so ARCHIVE_TAKE_COUNT=1 would be archiving the first and last unarchived link recursively until every link is archived.

Okay, with the tweaks above it is usable and does not grind the server to a halt. Using 850MiB of memory when idle still is quite a lot though, for 250 bookmarks. I mean a postgres database holding millions of rows idles at ~500MiB.

This is my stats for the month since I also noticed the issue of the background scripts and fixed some values in the environment to fix them:

ARCHIVE_TAKE_COUNT=1
ARCHIVE_SCRIPT_INTERVAL=30

Just double check the environment variables that are set in the worker and test them out accordingly:
