Sending comments sometimes takes actual minutes and loading the site takes a bit long too… is this due to the Reddit migration or cuz I’m european?

    • Unfortunately, a Lemmy instance currently scales vertically.

      To stop an instance from being overloaded, it needs more CPU/RAM on a single server.

      Lemmy’s horizontal scaling comes from more instances federating with eachother. Which is why there are a lot of comments and posts about “please pick a quiet instance”.

      I know people are trying to get a single instance to work across multiple servers, which would allow for load balancing and dynamic scaling.
      However, at the scale Lemmy is currently operating at: throwing bigger hardware at it is easier than getting Lemmy to autoscale and use more hardware.
      I imagine in a month or so, solutions will be developed to make horizontal scaling more accessible.

        • The protocols Lemmy uses rely on additional instances and federation to scale horizontally.
          That’s kind of the point of the fediverse. There shouldn’t be big instances.

          The issue is a lot of users want to be on the busy instances.
          Whilst it shouldn’t matter which instance you actually join and use, some instances might have community/moderation that aligns with how you want to experience Lemmy (eg beehaw)

          Lemmy hasn’t been developed for a single instance to scale horizontally. Throwing bigger hardware at it is the correct way to implement scaling when a project is this size/maturity.

          Having stateless middleware, running caches, sharding databases, database replication, read/write load balancing on databases, having the actual front end load balancers…
          It’s a difficult problem. Companies have entire teams that work on this, and it requires a lot of skill and attention to keep all the parts working correctly, and ensure things are fault tolerant.
          Most instances are run by volunteers and community funding.

          Like I said, hopefully Lemmy will move to a format that allows for easier scaling. But it’s a lot of work.
          There is probably more value in squashing bugs, improving user experience, adding some well-needed features, and any optimizations they find along the way - than there is in rebuilding the stack to support horizontal scaling.

          Remember, Lemmy has a core team of 2 developers.
          And this massive influx of users became apparent at the start of this month.
          It’s going to take some time, and things will be rough round the edges.
