Understanding the base approach to be "buy the pair of shoes that fit", can anyone provide estimates of how much memory usage would correlate to a number of users in an "active" community?
I'll be moving to a VPS solution with my hosting provider tonight and see they offer a range of options for RAM (300MB to 4GB) with unlimited bandwidth, storage, etc., no matter what RAM you select. So really my only variable here is RAM (which of course correlates positively to cost).
For week 1 they provide you the full 4GB of RAM and then scale back ater the first week to what meets your existing needs. However, since I'll be starting with a small community that i hope to grow, I really don't have any estimate as to what RAM setting might make sense with NN users.
The operative word being "active", would 300MB be enough to support and active community of 500 members? 1500? Or can this even be estimated?
