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 voilΓ . 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.

Is the sort algorithm still messed up? In other instances it shows more recent posts in the hot section.

Thank you for everything that you do!

Thanks for all the hard work and documentation!

Does browsing with Incognito/Private mode opens up new bugs, or does the refreshing thing kept the same principle? I should be stayed as logged on, but for some reason - after this update - whenever I open a new private tab from the tab I'm logged on I am indicated as not logged in.

This runs quite smoothly for me as a Persistent Web App, thanks for your hard work!

[–] thisisdee@lemmy.world 2 points 2 years ago

Comment testing on lemmy.world

Why posting/commenting on other communities = blazing fast, while here = takes about 3 to 8 seconds? Is it just me?

Still seeing a lot of 504s, and this is at a time where the site shouldn't be super busy

[–] Jodilye@lemmy.world 2 points 2 years ago

Love the update, all back up and running again :) I joined this morning after discovering this awesome Apollo replacement and was so disappointed that it was down already! Understand that the sudden surge must be huge, looking forward to seeing the data of amount of users gained by Lemmy!

Honestly praying this is the solution we all want and need!

[–] thaedrus@lemmy.world 2 points 2 years ago

Looks like everything is working well so far. Browsing from Wefwef and Liftoff.
