Within this thread/post, I'm hoping that we can collate a set of thoughts/guidance/advise for DCS users to assist with their system optimisation.  Such that instead of having to repeatedly state the same things to people with questions who were unable to find guidance using the search, that we can direct them to a single thread. In particular, the opening post will collate things, and I'm hoping that others will add useful recommendations that I can merge into the opening post, so please do
