I have a project with 65000 tags, but only 500 are used. Would removing the unused tags allow me to use a higher scan rate? I would like to achieve 250ms, or better.

Is there a way to find all tags that are in a container? I could then create a scan list for that window/container and optimize those that need to be fast and those that can be slower.
