I am looking for general guidance on spec'ing a machine to run an Ignition gateway. Recognizing that many factors impact gateway performance, are there certain factors (e.g. quantity of OPC tags) that are most important to consider when determining the necessary resources (i.e. CPU, RAM, storage)? We are in the early stages of planning a large system (100k+ tags, 100+ OPC connections). Any help would be appreciated! ---

"Light duty" would be single page Perspective apps running in Workstation, or Mobile, or single-tab browser sessions, displaying dashboards with real-time tags, up to an hour (-ish) of real-time trends, and pre-computed statistics for longer time… ---

Thank you! This is just what I was looking for.
