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 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.

Hopefully the performance issue will be resolved soon, I can imagine lots of new refugees will be migrating to this instance.

Can't edit profile settings / info. Pushing Save does nothing.

They're on virtual tin and didn’t configure properly. There are limits in the flat files you need to change by hand to get it to scale properly, it’s tricky.

[–] Gort 1 points 2 years ago

Thanks for being both informative and open about this issue. Hope it works out.

Edit: The first two versions of this post didn't seem to send: spinning post button. Maybe it's not fixed or it's struggling?

[–] kratoz29 1 points 2 years ago

Awesome, Jerboa revived!

[–] BeigeForce 1 points 2 years ago

Congratulations on the upgrade - thanks for hanging in there for the community!

[–] Apfm141 1 points 2 years ago

Nice work guys!

[–] phx 1 points 2 years ago

Works with Jerboa again (yay).

Kinda makes sense that multiple containers might scale better. The actual processes within the container may have some limitations in terms of how well they thread etc.

[–] DelvianSeek 1 points 2 years ago

Well done! Know that your efforts are greatly appreciated. Thank you!

[–] Myriadblue 1 points 2 years ago

Thank you so much for doing this! The having an instance this big really made the difference for leaving reddit. I really missed jerboa and am glad to have it back as a client.

[–] sheetmysharts 1 points 2 years ago

Thanks for the monster effort on the update, these things are never trivial.

[–] xc2215x 1 points 2 years ago

Good to see this for the Lemmy website. This will do a lot.

Bug I’m running into -

When my mobile browser (Firefox, iOS) language is set to something other than English, not content loads and I am unable to log in.

[–] wason 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.

[–] ThatGirlKylie 1 points 2 years ago

Awesome job! Already loving it here.
