Due to the recent @Soup’s post I have decided to do some housekeeping. I’ve been getting frustrated at lemmy’s performance at times as well and this simply was a wake up call, if you will.
I am sorry about no advance downtime annoucement - Sunday is the only day I can really put any meaningful amount of time into lemmy.
Things done today:
- Upgraded
databaseVM 1 core 2GB -> 2 cores 4GB. Double the compute, double the memory. - Adjusted database config to account for increased resources
- Adjusted
hugepagesconfig to account for increased database’s requests - Updated both lemmy and database VMs
- Rebooted the lot
Thank you for your patience. I will also use this moment of focus to write up a financial report in a separate post.
Also, thank you, @Soup!
EDIT: I’ve also marked all instances known to lemmy.cafe as active. What this means is that lemmy.cafe will now keep retrying to federate to everything very aggressively. This is a compute-intensive process and will also impact performance for a few hours, until exponential backoff kicks in. I’ve done it to revive any falsely-marked-as-dead instances; there’s no fix for it on lemmy itself.
Once again, thank you for all the hard work you put into maintaining the instance.
While you are at it, I wonder if you can check the configuration for pinned/featured posts.
It appears that lemmy.cafe instance doesn’t always show pinned posts at the top. For example:
https://lemmy.cafe/c/imageai@sh.itjust.works
If you refer to the original instance, there should be a pinned post with the title “[Community Challenge 50] The Space Race”.
I have seen a similar problem reported on sh.itjust.works matrix chat - in their case what helped was toggling the sticky post. I’ll ask there to do that for this community. You might also want to reach out to mods directly - they might get to do it sooner.
Supposedly this is a known federation bug, but I haven’t seen a bug report mentioned.
I believe it’s been re-stickied now!
