Hi Discourse Community! Recently I have been trying to improve the performance of my Discourse installation and clean up a little since my site has been growing exponentially lately. I have identified two issues, searched about them here but I don’t see a clear answer for some specifics, so I hop…

Mini-Update: Tried to tweak around the Unicorn Runners Settings but I don’t really know if there is a core-per-worker relation or is like a shared CPU kind of thing like CPU % x Second, is there a best practice for this? Also, have been reading about PostgreSQL to know how to get around that size b…

I strongly advise you to not override the Discourse defaults, which auto-close topics with more than 10k replies. There’s a reason we have this setting on by default. :scream: Beyond that, this problem of massive post_timings table is on our radar :satellite: and we are currently brainstorming ways…

I’ve got a site with a handful of >100K post mega topics. I told them that it was a mistake, but they wanted them anyway. They are complaining about performance issues. I’m hoping that I’ll soon be able to change the value back to the 10K default. It did cause me to learn some stuff about database …

[immagine] Paracelsus: Imagine a topic about Trump in general or one about the United States in general. Imagine a category about Trump in general or the United States in general. No one is going to read >10000 posts in a topic straight through. They just aren’t. At some point, you can just …
