I am trying to figure out what kind of hardware I need to run a phpBB 3 server for a fairly large community. When I say hardware, I mean CPU, RAM, and IO specs. When I say fairly large community, I mean a community of about 30,000 people that averages, let's say, 1,000 posts per day, with about 100 users active per day.
I have seen people discussing having 1 GB RAM for a phpBB 2 community of 5,000 users, but that is, of course, a bit old. Any ideas?
