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 @stanford@discuss.as200950.com and @sunaurus@lemm.ee 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 @sunaurus@lemm.ee 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!
Agreed!
I decided to create a user to show my appreciation for these types of updates. Love it. Hope to engage more with this thing now moving forward - let’s get this going 👍
So no more random sports posts at the top of every thread? That was a weird bug.
You WILL know the score
Scores will continue until morale improves!

That was because of websockets. Which are no more in this version so yes all those “random things” bugs from multiple tabs should be fixed.
I was so confused by those and kept backing out my feed and going back to the post, thinking I tapped on the wrong post or maybe the app opened the wrong post. I’d scroll down and find the right comments though, I couldn’t make any sense of it. Glad I wasn’t crazy lol
Red Sox forever! 🤪🤪🤪🤪🤪🤪🤪
This post encapsulates what I love about this place.
It’s almost like we’re talking to a normal human being rather than an evil overlord.
I for one welcome our new benevolent overlords
Don’t blame me, I voted for Kodos
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 shouldn’t be unreasonable but it is damn refreshing.
It’s cool we all want the new community to succeed and get live updates on things being fixed or worked on. There’s some shared misery in growing pains/bugs as we all stress test the system, but I think that only somehow brings more communal joy when the problems are fixed.
Agreed. Thanks for letting us nerd out
Thanks a lot for your hard work, take your time with your children
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.
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.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!
Only being on Lemmy.world for a day. It seems smoother …yes I am a reddit user trying to find a new home. 😂
Welcome!
I hope we can make this place even better together :)I’ve been on Lemmy for… four days? The traffic influx made the past 24hrs the least smooth it has been in my short stay so far, lol. The upgrade to 0.18 definitely did help though.
Lemmy feels much smoother now after hours of being overloaded, what changed?
Thanks again admin team, you rock!
Well done! Thank you for your efforts, cheers!
Good bloody job admins, thank you heaps for your perseverance on this.
Looks like the server is choking again, we’ve had ~7k new signups so far today 😅
Eyyyy, nice. I can use Jerboa again. Thanks for your work!
It still isn’t working for me, it is stuck in Local Active and can’t change filters. Probably something else though, no server version error now. I have been using Connect for Lemmy, which I’d never heard of but came up in the play store search. Seems to work fine, it’s some real early access out here!
Try closing the app and clearing the cache. If that doesn’t work, maybe consider reinstalling.
I should have given that a try, clearing the cache hadn’t worked, but the reinstall did. Thanks =)
Don’t forget to checkout Liftoff and Thunder, they are phenomenal Android apps. Also, both Boost and Sync are going to be launching early versions of their Lemmy apps soon!
So some strange behaviour: When I pressed the upvote arrows in 0.17.4, it’d immediately show this in the UI. Right now, it does not. The response appears quite slow. Is this a function of 0.18.1-rc or a function of the traffic of the Reddit-fugees?
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.
