Hi, Is it mandatory that we should have 2GB of Ram for Discourse. I am planning to use discourse for one of my forum. Please help me. Thanks

You don’t need 2 GB. Where did you see that? The minimum requirement is 1 GB as stated in http://www.discourse.org/faq and the setup document on GitHub.

No, 1GB is the minimum for a functional site. You can use 512mb for single user testing, it will sort of work. But a live public Discourse site on 512mb will be quite painful for everyone who tries to use it.

Depends on the number of users and requests I think. I run a small private instance with some old friends of mine. I have reduced the unicorn workers and the sidekiq concurrency. It works really well with a small amount of RAM.

Out of curiosity, is it known what components of discourse are the most resource hungry?

[image] rumpelsepp: It works really well with a small amount of RAM. How much is a small amount?

246 MB (unicorn) + 317 MB (sidekiq) = 563 MB But don’t forget you need redis and a database server as well.

Mine is running on the lowest tier VPS that Vultr.com offers, with 768MB of RAM + a swap file. It runs fine for the low traffic I have at the moment. In the future hopefully it will pick up a bit more and I’ll upgrade my RAM.

I have to say, there was a lot of… shock? from the phpList techies when we saw what the server requirements were. It was considered really quite extraordinary.

Yeah, PHP is really old technology, the COBOL of its time.

Does the server need 2GB of RAM?
