YSK: If you want faster and less buggy User experience, move to a smaller instance that is hosted close to you.
I have been using Lemmy for 20 days, at first I opened an account at Lemmy.world because you can join without writing a text and waiting approval. I have been enjoying the experience overall but despite the admin teans best efforts Lemmy.world has been experiencing some serious performance issues. If you want to avoid that join a smaller instance, preferably hosted in your country. I joined discuss.tchncs.de today and everything is so much faster it has added benefit of being able to see beehaw.org posts too. It will improve not only your but all other Lemmy.world users experience too.
Beehaw.org chose to defederate some big instances like lemmy.world because the beehaw admins feel like they can't moderate the inappropriate content entering their instance from big instances without proper mod tools.
They made a long post sharing their reasons but I can't find it at the moment.
