How do scanclasses affect memory tags?

We are trying to optimize the performance of our tag providers and I was curious if changing the scan rate on memory tags will accomplish anything. Does Ignition actually ‘scan’ anything in regards to memory tags?

No, the scan class rate (or tag group rate in 8.x) is irrelevant for memory tags.
