Looks like it works.
Edit still see some performance issues. Needs more troubleshooting
Update: Registrations re-opened We encountered a bug where people could not log in, see https://github.com/LemmyNet/lemmy/issues/3422#issuecomment-1616112264 . As a workaround we opened registrations.
Thanks
First of all, I would like to thank the Lemmy.world team and the 2 admins of other servers @[email protected] and @[email protected] for their help! We did some thorough troubleshooting to get this working!
The upgrade
The upgrade itself isn’t too hard. Create a backup, and then change the image names in the docker-compose.yml and restart.
But, like the first 2 tries, after a few minutes the site started getting slow until it stopped responding. Then the troubleshooting started.
The solutions
What I had noticed previously, is that the lemmy container could reach around 1500% CPU usage, above that the site got slow. Which is weird, because the server has 64 threads, so 6400% should be the max. So we tried what @[email protected] had suggested before: we created extra lemmy containers to spread the load. (And extra lemmy-ui containers). And used nginx to load balance between them.
Et voilà. That seems to work.
Also, as suggested by him, we start the lemmy containers with the scheduler disabled, and have 1 extra lemmy running with the scheduler enabled, unused for other stuff.
There will be room for improvement, and probably new bugs, but we’re very happy lemmy.world is now at 0.18.1-rc. This fixes a lot of bugs.
Really like seeing posts like this that explain what’s going on. Thanks for all the hard work!
The transparency is so refreshing
Seeing this post immediately made my ditch my neglected Lemmy instance to sign up for an account on this server. Thanks for the hard work.
agreed. as others have stated. Transparency. But also, new software, new tech (in a way, the fediverse/activity pub), and hopefully a new beginning. Happy to be here. If not technically on the ground level (lemmy has been around for a short time before we knew reddit was going to implode), close to it!
It has been near unusable since the upgrade.
It seemed to work fine at first, but starting today I’m noticing a huge number of async failures; I’ve had to refresh the page in order to get almost anything (comments, posts, communities, list of communities, profiles, etc) to load.
Same here, async errors happening frequently ☹️
Same, first time since 24h I can open lemmy.world community in Jerboa without being greeted with a blank screen :-(

Yep. So much lag, lots of ‘network error’ in Jerboa.
Never change, free software </3
Edit still see some performance issues. Needs more troubleshooting
Federation overheard is putting a lot of load on servers. Creating one task for every single post, comment, and vote in RAM-only queue… pending changes: https://github.com/LemmyNet/lemmy/pull/3466
Lol.
A bit off topic, but does anyone else hate how when you click on a post and then go back, the page auto-resets to the top? Wish it would remember how far down you scrolled and return to that point.
I’ve always opened in a new tab (middle/ctrl click)
How are you doing that in the app (Jerboa)?
Not
Not
It is something being worked on. I think there was a pull request that’s already merged, it just needs to be released I think.
Thanks a lot for your hard work, take your time with your children
This post encapsulates what I love about this place.
How so?
Admin communicating information about the site to users like genuine human beings, instead of the corporate-sanitized pablum reddit admins speak in? Yeah that’s refreshing.
It’s almost like we’re talking to a normal human being rather than an evil overlord.
The update is good. Just needs more troubleshooting

Huge thanks to the lemmy.world team over the last couple of days to scale and maintain the instance! There’s a link for donating on the sidebar for lemmy.world - just a couple bucks a month can help us support this instance!
Thank you for everything you are doing to update the community and make this space better for everyone!
Looks like the server is choking again, we’ve had ~7k new signups so far today 😅
U peeps are awesome. 🙏🙇
For everyone experiences issues during the login,
This is caused by an issue in the latest RC of the Lemmy UI. It’s already been reported, and ruud will probably decide how to deal with it tomorrow.
The current workaround
Make sure you are on the main page (https://lemmy.world) and not looking at any posts or something like that before hitting the login button.
If you encounter other issues, please make sure to clear the browser cache. The latest upgrade also made changes to the API, which can cause issues with the cached version of the website.Lemmy feels much smoother now after hours of being overloaded, what changed?
Thanks again admin team, you rock!
So no more random sports posts at the top of every thread? That was a weird bug.
When not overloaded the site works better now than ever. But in general this instancen is kind of unusable now as everything is too slow.
I haven’t really noticed any major issue. It’s a bit slow but not unusable
