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
database VM 1 core 2GB -> 2 cores 4GB. Double the compute, double the memory.
- Adjusted database config to account for increased resources
- Adjusted
hugepages config 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.
