Let me be clear, I'm asking an impossible question. I know I'm asking an impossible question and apologize in advance. I'm just hoping I can get a little guidance to make a better guess then I can on my own.
I'm building a new forum. But unlike most new forums it has a pretty good size out of the box following. We are refugees from a forum site that is closing down at the end of the month, and we are taking several of the community and creating a new environment for them to continue to exist in. The idea is to be community-owned, community-run and not have to deal with this again.
The problem I have is that the current platform doesn't give us data on page views. I can get data on posts and followers, but I only can get posts at a daily level, and followers obviously is a pretty miss leading number since many of them clicked the follow button once years ago and then forgot about the forum.
All in with all the sites were are looking at so far there are about 250,000 followers and up to about 10,000 posts in a day. Obviously, this is going to tapper off with a move.
I'm trying to figure out how to size a server. I'm leaning toward a low range VPS as it will likely be easier to upgrade resources later if we need to. At the same time, another member is willing to front all the costs annually. I want to be very respectful of her and not blatantly over spend. Having never run PHPBB before and not having great numbers to go off of, I'm not even sure where to start and thought I could get some opinions here. Don't worry, when
I miss-size it I'm not going to blame any of you.
Thanks in advance for tolerating this obnoxiously impossible question.
