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 voilร . 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.

It seems that I can't log out in my browser. The page simply reloads after clicking the button.

Half the time when I comment, it just spins. :( Edit: Apparently when I comment it posts, but just shows spinning until I manually refresh. Must be on my end.

Nice work!

we created extra lemmy containers to spread the load. (And extra lemmy-ui containers).

Is Rust HTTP server running into thread limits? database connection pooling? All kinds of internal questions bout that solution.

[โ€“] [email protected] 3 points 2 years ago

I don't know rust. But there were 150 database connections setup by lemmy, but only about 15 of them were used, the rest idle.
