Side note: it should be possible to tweak some config parameters to optimize the memory usage or cpu usage of quickwit. Ask us on the discord server next time :)
Yeah, I was a little bit surprised it was so close. And I've been using tantivy (the library which powers quickwit afaik) in another side project where it used comparatively less.
Might jump in there then as an excuse to fiddle a bit more with the homelab soon then :)
