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.

    Thanks, appreciate your input.

    If postgres is the scaling limit on most deployments, I assume normal postgres scaling via replicas and sharding would apply.

    Is the frontend amenable to heavy caching for non-logged-in views?

      Yes horizontal scaling of Postgres probably works especially together with running multiple Lemmy backends behind a load balancer. But I am not aware of anyone running such a setup right now.

      Caching is being worked on right now and should be available together with the no-websockets improvement very soon.
