I split this off so we could all explore this more. For neophytes like me, this is a very useful topic that I fear would hijack the original thread.
So, I'm looking into this more now. My situation is that I have multiple WP installs on a dedicated server with 4GB. Now I'm thinking I want to bump that memory up to at least 8GB but I don't know enough about servers to know if it would even be able to use it. SO, my next step is to speak with the host about the max I can get on the box along with prices. This will set the ceiling for me. Then I can back into the rest of the setup based on what I have to work with.
