Status update July 4th
Just wanted to let you know where we are with Lemmy.world.
Issues
As you might have noticed, things still won’t work as desired… we see several issues:
Performance
- Loading is mostly OK, but sometimes things take forever
- We (and you) see many 502 errors, resulting in empty pages etc.
- System load: The server is roughly at 60% cpu usage and around 25GB RAM usage. (That is, if we restart Lemmy every 30 minutes. Else memory will go to 100%)
Bugs
- Replying to a DM doesn’t seem to work. When hitting reply, you get a box with the original message which you can edit and save (which does nothing)
- 2FA seems to be a problem for many people. It doesn’t always work as expected.
Troubleshooting
We have many people helping us, with (site) moderation, sysadmin, troubleshooting, advise etc. There currently are 25 people in our Discord, including admins of other servers. In the Sysadmin channel we are with 8 people. We do troubleshooting sessions with these, and sometimes others. One of the Lemmy devs, @nutomic@lemmy.ml is also helping with current issues.
So, all is not yet running smoothly as we hoped, but with all this help we’ll surely get there! Also thank you all for the donations, this helps giving the possibility to use the hardware and tools needed to keep Lemmy.world running!
cloudfront helps a lot with the client and is absolutely compatible with lemmy if you set it up correctly. possibly it could also help cache api responses, i haven’t looked into that part yet.
the database, on the other hand, would need a nearly full rewrite. lemmy uses postgres and dumping it for something else would be a huge pain for the entire federated community. it could probably tear it in half.
there’s also the issue of pictrs, which uses a stateful container and isn’t yet able to use an external database which would allow you to scale it horizontally. resolving that one is on the roadmap though, and for the most part you can aggressively cache the pictrs get requests to alleviate the read-side load.
but whatever the solution is, it kinda needs to be as simple as developing and deploying docker containers you can throw anywhere. the vendor-agnostic setup is a very important part of the open-source setup of lemmy. it’s fine to build on top of that, but currently anyone with docker-compose installed can run the service and that really should be retained.
