Lemmy resource usage (join-lemmy.org)

Why does the official Lemmy docu say:

Lemmy uses roughly 150 MB of RAM in the default Docker installation. CPU usage is negligible.

whereas the Node.js server alone (dessalines/lemmy-ui container) consumes over 100 MB?

I would have easily ordered a 2 GB VPS in the first place, but I trusted the documentation to be up-to-date.

Yeah I'm not really sure about the RAM usage, I guess technically the lemmy server itself is eating 150.

Actually looking at ctop.. I think they're only mentioning the lemmy server itself in the docs. ¯_(ツ)_/¯

It appeared that lemmy-ui also causes random cpu spikes of load ca. 25.0 which made my small VPS unresponsive for a few minutes every few hours.

I have observed great performance improvement with mlmym but it lacks some basic functionality, so now I'm using Photon and with satisfactory result (btop):

Glad to hear Photon has satisfactory performance, the new Svelte 5 version (use tag v2.0.0-rc.5) might even run faster, might want to give that a try.

True, 30M of footprint right now. I also decreased postgres hardware limitations as it was consuming a lot more memory than lemmy-ui. It was probably the culprit of those spikes but I'll stay with Photon anyway :)
