Lemmy hardware / VPS requirements? (beehaw.org)

Hello, all. I'm considering creating a Lemmy instance in order to facilitate migration of a moderately sized reddit community to the fediverse.

The community is about 150k users with around 1.5M pageviews per month.

I don't expect everyone to come with the migration, but I would expect a significant portion to do so. Perhaps half.

How do I go about capacity planning / sizing for such an instance? Is Lemmy designed to operate at this scale?

Thanks for your input.

Lots of unknowns right now. The best might be to look for a VPS provider that allows scaling up relatively easily.

Besides some low hanging fruits that are being worked on right now, it is simply unknown as no Lemmy instance has so far operated at this scale. The techstack (rust and postgres) is relatively performant though. Main bottleneck is likely going to be the database for now.

I'd also love to hear admin experiences about bottlenecks and scaling limits they see on their instances and ways they've found to address them (besides throwing more hardware at it)
