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.

This is awesome. Was a fun read too. Super cool to see what was going on behind the scenes.

Thank you! I’m hoping this solves a lot of the issues!

0.18 looks a lot better. Far better use of screen real estate on PCs.

Lag is still very prevalent though. Page loading, upvote delay. It's frustrating.

Live comments (like on new Reddit) does not seem to be working on 0.18, so I have to manually refresh the page each time. That also resets the comment sort to Hot, causing further annoyance.

Thanks for the hard work!, I had an issue the first minutes where every time I logged in I got logged in with a different stranger account, now it doesn't happen but I can't login haha.

Would you mind sharing your docker-compose.yml file (sanitized, of course)? I am trying to spin up an instance on Google Cloud.

Hey ruud. Is there Patreon we can sign up to help with the hardware upgrades/upkeep?

thank you for upgrading! I much prefer the new URL structure of this version

[–] [email protected] 1 points 2 years ago

Browser still not working for me. The interface loads but there's no content. Also can't login on browser, after entering user and password and clicking login nothing happens.

[–] [email protected] 1 points 2 years ago

@ruud Thank you for the work you guys are doing. Without you, we wouldn't have an organized place to go after Reddit and Twitter.

[–] [email protected] 1 points 2 years ago

The speed and responsiveness of just scrolling is already infinitely better. Thanks :)!!!
