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.

Really like seeing posts like this that explain what's going on. Thanks for all the hard work!

[–] ayyndrew@lemmy.world 1 points 1 year ago (1 children)

The transparency is so refreshing

[–] gfdoto@lemmy.world 0 points 1 year ago

Seeing this post immediately made my ditch my neglected Lemmy instance to sign up for an account on this server. Thanks for the hard work.

[–] lenninscjay@lemmy.world 1 points 1 year ago

agreed. as others have stated. Transparency. But also, new software, new tech (in a way, the fediverse/activity pub), and hopefully a new beginning. Happy to be here. If not technically on the ground level (lemmy has been around for a short time before we knew reddit was going to implode), close to it!

[–] Sneckster@lemmy.world 4 points 1 year ago (1 children)

This post encapsulates what I love about this place.

[–] deweydecibel@lemmy.world 1 points 1 year ago

How so?

Admin communicating information about the site to users like genuine human beings, instead of the corporate-sanitized pablum reddit admins speak in? Yeah that's refreshing.

[–] marsokod@lemmy.world 3 points 1 year ago

Thanks a lot for your hard work, take your time with your children

[–] free@lemmy.world 2 points 1 year ago

U peeps are awesome. πŸ™πŸ™‡

[–] Dogs_cant_look_up@lemmy.world 2 points 1 year ago

So no more random sports posts at the top of every thread? That was a weird bug.

[–] Anaralah_Belore223@lemmy.world 1 points 1 year ago* (last edited 1 year ago)

The update is good. Just needs more troubleshooting

Trying to edit this comment

A bit off topic, but does anyone else hate how when you click on a post and then go back, the page auto-resets to the top? Wish it would remember how far down you scrolled and return to that point.

[–] minimar@lemmy.world 0 points 1 year ago (1 children)

I've always opened in a new tab (middle/ctrl click)

[–] guyman@lemmy.world 0 points 1 year ago (2 children)

How are you doing that in the app (Jerboa)?

[–] flamekhan@lemmy.world 1 points 1 year ago

Huge thanks to the lemmy.world team over the last couple of days to scale and maintain the instance! There's a link for donating on the sidebar for lemmy.world - just a couple bucks a month can help us support this instance!

[–] xikufrancesc@lemmy.world 1 points 1 year ago

How beautiful and cute the new lemmy world looks. thanks boss.

Que bonito y lindo se ve el nuevo lemmy world. gracias jefe.

[–] rustytree@lemmy.world 1 points 1 year ago

Nice. I can use jerboa now.

[–] Magister@lemmy.world 1 points 1 year ago* (last edited 1 year ago)

I cannot connect with Jerboa, it always says user or password incorrect πŸ™

Edit: worked after a few minutes

[–] Secret300@lemmy.world 1 points 1 year ago

we created extra lemmy containers to spread the load. (And extra lemmy-ui containers). And used nginx to load balance between them.

Had no idea nginx did that. There's so much I need to learn

[–] tmpod@lemmy.pt 1 points 1 year ago (1 children)

Awesome work!

I'd like to know more about the exact container topology you have, since I may try something similar on my instance as well.
Is it something like this?

[–] ruud@lemmy.world 1 points 1 year ago

Yeah with nginx doing load balancing

[–] BitOneZero@lemmy.world 1 points 1 year ago

Edit still see some performance issues. Needs more troubleshooting

Federation overheard is putting a lot of load on servers. Creating one task for every single post, comment, and vote in RAM-only queue.... pending changes: https://github.com/LemmyNet/lemmy/pull/3466

[–] Merulox@lemmy.world 0 points 1 year ago (1 children)

Profile pictures on user profiles are still stretched, and now the upvote arrows doesn't turn blue until you refresh the page when you press it

Other than that, this is a fantastic design update

[–] phrankygee@lemmy.world 0 points 1 year ago* (last edited 1 year ago) (1 children)

When I sort my comments by β€œTop Week” I get stuff from 10 days ago.

Edit: Actually, no matter what time period I select, I still see old posts from 10 days ago.

[–] Merulox@lemmy.world 1 points 1 year ago

Huh, that's odd, it's working fine for me.

[–] Tag365@lemmy.world 0 points 1 year ago (3 children)

I had a strange bug today where I wasn't able to upvote comments. So I cleared out my website data like the website suggested and I started having problems logging in. It would log in but then when I refreshed it wasn't logged in anymore. It stopped after a while but then when I clicked on an old tab when I refreshed I was logged out again. So, the log in issue must be something to do with how iOS Safari handles web cache on tabs.

[–] DarkWasp@lemmy.world 1 points 1 year ago* (last edited 1 year ago)

I’m having major issues with upvoting in safari on iPad. Seems like it will take either 10 seconds or so and work or not react at all.

Edit: Wiping all safari browsing history/clearing everything fixed it for 20 mins or so and it’s back to behaving the same way again.

[–] normalmighty@lemmy.world 1 points 1 year ago* (last edited 1 year ago)

Upvotes aren't responding for me, but the comment is marked as upvoted when I refresh the page. I think it just isn't rerendering on the frontend.

Edit: same thing is happening when posting comments. I refresh and the comment was posted, but without refreshing it's marked as loading forever.

[–] Tag365@lemmy.world 0 points 1 year ago (1 children)

I suddenly got "logged out" again, but when I opened a new tab and went to Lemmy.world I was still logged in.

[–] tpfm@moth.social 0 points 1 year ago (1 children)

@Tag365 @Tag365 You prolly ended up in another instance (lemmy.x)

[–] Tag365@lemmy.world 1 points 1 year ago

Wrong, it was the same instance, merely the tab was unloaded and then reloaded.

[–] MyOpinion@lemmy.world 0 points 1 year ago (2 children)

It has been near unusable since the upgrade.

[–] infotainment@lemmy.world 1 points 1 year ago

It seemed to work fine at first, but starting today I'm noticing a huge number of async failures; I've had to refresh the page in order to get almost anything (comments, posts, communities, list of communities, profiles, etc) to load.

[–] guyman@lemmy.world 0 points 1 year ago

Yep. So much lag, lots of 'network error' in Jerboa.

Never change, free software </3

[–] dingdong@lemmy.world 0 points 1 year ago

hehe first :)
