#lemmy/#kbin has a problem that #mastodon hasn’t even attempted to solve; groups and what happens when they get popular.
#Communities, #groups, #magazines, whatever they are called are implemented as #Actors in #ActivityPub. They are basically just *very* popular users who boost a *lot*.
You can’t just distribute them across instances the way normal actors do. Whichever server hosts @technology@lemmy.ml or @technology@beehaw.org is going to get HOSED on the regular.
Funny how you say it’s not a problem, then go on to describe the problem that needs to be dealt with. Dealing with scaling is a problem, and it’s a problem that costs money.
Posts like this: https://lemm.ee/post/58472 suggest it is a problem. The rise in traffic seen by Lemmy in the last few days is absolutely tiny compared to a site like reddit, and already instances are struggling to cope. The recent growth in user registrations represents only about 0.007% of reddit’s active user base. (~60K new Lemmy users vs 861,000,000 active monthly reddit users). A site like reddit costs millions to run.
There are 190+ Lemmy instances last time I checked, yet almost all the brunt of this load has been borne by a handful of servers, which see an inordinate amount of traffic while 100+ other servers sit around idle. Why should a handful of “lucky” servers have to pay all the hosting costs? What if a volunteer-run instance explodes to reddit-like levels of popularity? It will simply fold, unless the volunteer has serious money to throw at the problem.
