I like the future-minded Discourse, and while I’ve also been following Flarum, which finally went stable recently, ideally I’d love to give feature-superior Discourse a shot by migrating from vBulletin.
However, my biggest issue is technical requirements. My community is sponsored with a VPS by a hosting company. I know DigitalOcean is recommended and if a regular VPS is employed, Discourse may run with problems.
Because I have the flexibility to customize this VPS to any specifications, what should these specs be that would guarantee good performance, if that’d even make a difference?
Discourse should run on any VPS that is using KVM for virtualisation (a quick way to check is to see if the host allows installing a custom OS) with 1GB of RAM.
If you have a particularly busy site you may benefit from more RAM and powerful CPU.
Do you know roughly how many pageviews you get daily?
