Composite issues

Although composites can simplify linking and make understanding logic flow easier, they always introduce performance issues. Perhaps the biggest issue is that once you link a dynamic value to a composite, for example the out of a proxy point, it essentially pinned into the subscribed state. This means that proxy point will always be polling (regardless of any other usage).

In addition, each item exposed in a composite represents a link, where each link consumes some small amount of station resources. If used excessively, composites could noticeably reduce the total capacity of the station.
