Here is the SAR report for the server. Remember we are running at half the cores, half the memory that is recommended - mostly just as an experiment to see how much is really needed for things to be responsive. And so far, ingesting five servers, it is working just fine. We will be adding more servers and keeping an eye on things to see how the performance is and will grow the server if we need to. We are trying to learn from this so that we will have better capacity information. But for a smaller company it looks like a very small server will work just fine. No question that the server is busy, but now that it is up and running and no longer handling the initial setup, it's nowhere near being fully loaded.
