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.

Are you hosting on AWS?

Thanks so much for all your hard work, love Lemmy world! Enjoy the time with family!

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.

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

Thanks for all your work! Love the new look and it’s working great now

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

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

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.

YEAH BABEYYY

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

[–] darkbaron202@lemmy.world 2 points 2 years ago

thank u for letting us know what happening behind the scene. Me myself is a sysadmin and really love to read story about scaling up servers and it actually works! Once again. Thank you.

Thank you for the hard work! Enjoying Lemmy.world quite a bit. :)

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

Love the teamwork

[–] Djangofett@lemmy.ca 2 points 2 years ago

Showing us the true value of horizontal instead of vertical scaling! Kubernetes when?

[–] kratoz29@lemmy.world 2 points 2 years ago

Seems that sometimes the hot algorithm gets messed up :/

[–] mx3m@lemmy.world 2 points 2 years ago

Much love for your work

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

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

[–] Ryumast3r@lemmy.world 2 points 2 years ago

Will confirm at least for me I'm no longer having any issues.

Thank you for all your hard work!

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