I'm considering using snitz over mySQL for a web community.
What I would like to know is any rules of thumb for estimating the disk space required and likely subsequent band width.
I realise that these things will vary depending on size of post etc but I'm hoping there might be some ROTs for estimating what kind of web hosting SLA I'll need.
Not sure what you mean by Snitz over mySQL .. Snitz uses a database it could even be mySQL if you want.
There really is no hard and fast rule though becuase post sizes do vary a lot, the forum files themselves will ocupy less than a couple of meg disk space and your database initially will only be a few MB as well. I've one forum with about 60,000 posts and the total database size is about 100-120MB. Bandwidth the same applies really, depends on how busy the forum will be.
I'm fairly sure that database size won't be too bad with it being mainly text stored.
What I'm keen to know is that if you get a 100 hits per day, what is the average bandwidth or traffic used type of thing.
I'm thinking that reading a thread will cause at least one page to be generated and would like to know if people have some guidelines on average traffic vs user hits or maybe vs reads + posts per day.
