I have a new install of Discourse, where I imported a vBulletin forum with about 2 million posts and anywhere from 200-1000 daily active (concurrent) users.
I launched today on a Digital Ocean droplet with 6 vCPUs and browsing the site was pretty rough at the beginning … very slow, 504 errors, etc… I resized it to 16 vCPUs, and it’s working better but I am still getting 504 timeouts pretty often.
Is there a guide anywhere on what can be configured in nginx to help use the available resources better?
Load average is still pretty high.
EDIT: I realize I didn’t rebuild after resizing, and maybe that will take into account the new resources?
