Its now running on a dedicated server with 6 cores/12 threads and 32 gb ram. I hope this will be enough for the near future. Nevertheless, new users should still prefer to signup on other instances.
This server is financed from donations to the Lemmy project. If you want to support it, please consider donating.
It’s a single, dedicated server from ovh.com for 60 euros per month.
Is Lemmy made with horizontal scaling (a.k.a. launching more instances and have a load balancer proxy the requests to the various instances) in mind? It could help larger instances like lemmy.ml managing the load better rather than just putting it on a beefier machine.
You should be able to do that without problems. However the main bottleneck is the database, I think some people want to experiment with read replicas. However as developers we would rather focus on optimizations which will benefit everyone, not only the largest instances.
