Interesting username you have there.

I don't see why you don't accept "it's Rails." There are other issues as sibling comments have pointed out, but by starting with an ecosystem known to have performance limitations, this sort of outcome is inevitable, is it not? I'm sure the Mastodon team were never expecting the degree of usage which has been thrust upon its larger instances, but now that it has happened and the limitations have become apparent, I'd encourage people who are interested in setting up fediverse/"Mastodon network" instances to consider the alternatives to Mastodon, however paltry they currently are.

I know that the Pleroma front end and its forks are written in something called Elixir, which I have no idea about but I can't imagine it could be much worse than Ruby. What I'd really like to see is something written in a language known to be actually fast, though - PHP or Lua.
