Lemmy development really needs another couple weeks or a month. There are over 100 instances peering and it's really pushing the database systems hard with the 100,000 users already. Database tuning and query optimization in the code is the order of the day. I also think some of the new front-end apps for web and smartphones would help.
I'm genuinely asking and don't mean this the way it sounds, but is this supposition or have you observed this yourself?
Everyone says their own instances aren't very resource intensive. Even the larger instances like lemmy.world don't seem to have huge specs.
Although there's a lot of subscriptions there doesn't seem to be an overwhelming amount of content being produced. The most active threads in /home have like 150 comments over 2 days? I don't have the data and this really is mere supposition but it just doesn't seem like that much load.
I did see they pushed a new version with some db optimisations so that's probably an indicator that you're right. Also things just feel unstable. Unusually long page load times or 500 errors just occasionally. Things definitely aren't great I'm just not certain that db linkages are the problem.
Yes, and I've been building social media message systems since 1984, and I'm a published author on messaging systems. I described some of the data integrity and sever malfunctions on multiple systems that have small to large numbers of users, including my own system on Oracle Cloud that has only me as a developer/user. Example of how it is failing: https://lemmy.ml/comment/616698
