A server with users who do join very busy rooms, can easily eat 4 cores and

16GB of RAM. Or more. Or even much more. If you have a public server, where
unknown people can register new accounts, you'll probably need a bit more
oompf (and [moderation](draupnir)).
During its life, the server may need more resources, if users change
their behaviour. Or less. There's no one-size-fits-all approach.

changing the architecture from monolithic to worker-based once the server is
